Point set distributions are one of the three distribution formats. They are stored as a list of x-y coordinates representing both discrete and continuous distributions.
One complication is that it's possible to represent invalid probability distributions in the point set format. For example, you can represent shapes with negative values, or shapes that are not normalized.

### fromDist
Converts the distribution in question into a point set distribution. If the distribution is symbolic, then it does this by taking the quantiles. If the distribution is a sample set, then it uses a version of kernel density estimation to approximate the point set format. One complication of this latter process is that if there is a high proportion of overlapping samples (samples that are exactly the same as each other), it will convert these samples into discrete point masses. Eventually we'd like to add further methods to help adjust this process.

Squiggle is still very early. The main first goal is to become stable. This means having a clean codebase, having decent test coverage, and having a syntax we are reasonably confident in. Later on, there are many other features that will be interesting to explore.
Squiggle is still very early. The main first goal is to become stable (to reach version 1.0). Right now we think it is useable to use for small projects, but do note that there are very likely some math bugs and performance problems.
## Programming Language Features
- Equality (a == b)
- If/else statements
- Arrays
- Tables / Matrices
- Simple objects
- A simple type system
- Simple module system (`Dist.Normal` instead of `normal`)
- A simple time library & notation
- Optional and default paramaters for functions
- Anonymous Functions (This is particularly convenient in cases where tiny functions are submitted in forecasting competitions)
- A notation to limit the domain of functions. For example, maybe a function only applies for t=[2 to 20]
- Custom parser (Right now we're using Math.js's parser, which doesn't give us much flexibility)
- "Partial-domain" distributions. For example, maybe someone has a distribution for when AGI will happen, but doesn't want to make any estimates past 2200.
- Some story for tests
- Much better code editor integration
## Distribution Features
`Distribution.fromSamples([])`
Converts a list of samples, for example, from Guesstimate, into a distribution shape. Maybe takes a list of optional parameters.
`Distribution.fromCoordinates({xs, ys})`
Convert XY coordinates into a distribution. Figure out a good way to do this for continuous, discrete, and mixed distributions.
There are many important distribution types that Squiggle doesn't yet support. Some key functions we'd like include:
[Metalog Distribution](https://en.wikipedia.org/wiki/Metalog_distribution)
Add the Metalog distribution, and some convenient methods for generating these distributions. This might be a bit tricky because we might need or build a library to fit data. There's no Metalog javascript library yet, this would be pretty useful. There's already a Metalog library in Python, so that one could be used for inspiration.
@ -40,15 +29,6 @@ Takes a distribution and smoothens it. For example, [Elicit Forecast](https://fo
**Probabilities**
Right now Squiggle mostly works with probability distributions only, but it should also work smoothly with probabilities.
**Scoring**
Have functions to score probabilities, probability distributions, and functions that return probability distributions.
**Full javascript library**
A full Javascript library that accesses most of the probabilistic functionality of Squiggle, but can be used directly in javascript functions.
**Importance & quality scores**
Workflows/functionality to declare the importance and coveredness of each part of the paramater space. For example, some subsets of the paramater space of a function might be much more important to get right than others. Similarly, the analyst might be much more certain about some parts than others. Ideally. they could decline sections.

This interface should also be able to handle changing Squiggle values. This is because people would be likely to want to update their functions over time, and that should be taken into account for scoring.
**Easily call other functions**
It would be great to be able to call other people's Squiggle functions, from other Squiggle functions. This could raise a whole bunch of challenging issues. Additionally, it would be neat to call other data, both from knowledge graphs, and from regular APIs. Note that this could obviously complicate scoring a lot; I imagine that either easy scoring, or simple data fetching, would have to accept sacrifices.

**Correlated uncertainties**
Right now there's no functionality to declare that two different distributions are correlated.
**Static / Sensitivity Analysis**
**Static / sensitivity analysis**
Guesstimate has Sensitivity analysis that's pretty useful. This could be quite feasible to add, though it will likely require some thinking.
**Annotation**
It might be useful to allow people to annotate functions and variables with longer descriptions, maybe Markdown. This could very much help interpretation/analysis of these items.
**Randomness Seeds**
**Randomness seeds**
Right now, Monte Carlo simulations are totally random. It would be nicer to be able to enter a seed somehow in order to control the randomness. Or, with the same seed, the function should always return the same values. This would make debugging and similar easier.
## Major Standard Language Features
- Some testing story.
- A custom code highlighting format.
- Possibly a decent web GUI (a much more advanced playground).
- A VS Code extention and similar.
## Bugs
- Discrete distributions are particularly buggy. Try `mm(1,2,3,4,5,6,7,8,9,10) .* (5 to 8)`
## New Functions
### Distributions
```js
cauchy();
pareto();
metalog();
```
Possibly change mm to mix, or mx(). Also, change input format, maybe to mx([a,b,c], [a,b,c]).
### Functions
```js
samples(distribution, n);
toPdf(distribution);
toCdf(distribution);
toHash(distribution);
trunctate(distribution, leftValue, rightValue);
leftTrunctate(distribution, leftValue);
rightTrunctate(distribution, rightValue);
distributionFromSamples(array, params);
distributionFromPoints();
distributionFromHash();
```
**Caching/memoization**
There are many performance improvements that Squiggle could have. We'll get to some of them eventually.

Probability distributions have several subtle possible formats. Three important ones that we deal with in Squiggle are symbolic, sample set, and point set formats.
_Symbolic_ formats are just the math equations. `normal(5,3)` is the symbolic representation of a normal distribution.
When you sample distributions (usually starting with symbolic formats), you get lists of samples. Monte Carlo techniques return lists of samples. Lets call this the “_Sample Set_” format.
Lastly is what Ill refer to as the _Graph_ format. It describes the coordinates, or the shape, of the distribution. You can save these formats in JSON, for instance, like, `{xs: [1, 2, 3, 4, …], ys: [.0001, .0003, .002, …]}`.
Lastly is what Ill refer to as the _Point Set_ format. It describes the coordinates, or the shape, of the distribution. You can save these formats in JSON, for instance, like, `{xs: [1, 2, 3, 4, …], ys: [.0001, .0003, .002, …]}`.
Symbolic, Sample Set, and Graph formats all have very different advantages and disadvantages.

- Very easy. Just sample a bunch of times. The regular way is to randomly sample (This is trivial to do for all distributions with inverse-cdf functions.) If you want to get more fancy, you could provide extra samples from the tails, that would be weighted lower. Or, you could take samples in equal distances (of probability mass) along the entire distribution, then optionally shuffle it. (In the latter case, these would not be random samples, but sometimes thats fine.)
**How to Visualize**
Convert to graph, then display that. (Optionally, you can also convert to samples, then display those using a histogram, but this is often worse you have both options.)
Convert to point set, then display that. (Optionally, you can also convert to samples, then display those using a histogram, but this is often worse you have both options.)
**Bonus: The Metalog Distribution**
The Metalog distribution seems like it can represent almost any reasonable distribution. Its symbolic. This is great for storage, but its not clear if it helps with calculation. My impression is that we dont have symbolic ways of doing most functions (addition, multiplication, etc) on metalog distributions. Also, note that it can take a fair bit of computation to fit a shape to the Metalog distribution.
## Graph Formats
## Point Set Formats
**TL;DR**
Lists of the x-y coordinates of the shape of a distribution. (Usually the pdf, which is more compressed than the cdf). Some key functions (like pdf, cdf) and manipulations can work on almost any graphically-described distribution.

- Not as accurate or fast as symbolic methods, where the symbolic methods are applicable.

**Converting to Symbolic Formats**
- Okay, if you are okay with a Metalog approximation or similar. Metaculus uses an additive combination of up to [Logistic distributions](https://www.metaculus.com/help/faq/); you could also fit this. Fitting takes a little time (it requires several attempts and some optimization), can be arbitrarily accurate.
- If you want to be very fancy, you could try to fit graph distributions into normal / lognormal / etc. but this seems like a lot of work for little gain.

## Point Set Distributions Conversions
Point Set conversions are done with [kernel density estimation](https://en.wikipedia.org/wiki/Kernel_density_estimation), which is lossy. This might be particularly noticeable in cases where distributions should be entirely above zero.
In this example, we see that the median of this (highly skewed) distribution is positive when it's in a Sample Set format, but negative when it's converted to a Point Set format.
<SquiggleEditor
defaultCode={`dist = SampleSet.fromDist(5 to 100000000)
{
sampleSetMedian: quantile(dist, .5),
pointSetMedian: quantile(PointSet.fromDist(dist), .5),
dist: dist
}`}
/>
---
This can be particularly confusing for visualizations. Visualizations automatically convert distributions into Point Set formats. Therefore, they might often show negative values, even if the underlying distribution is fully positive.
We plan to later support more configuration of kernel density estimation, and for visualiations of Sample Set distributions to instead use histograms.
## Sample Set Correlations
Correlations with Sample Set distributions are a bit complicated. Monte Carlo generations with Squiggle are ordered. The first sample in one Sample Set distribution will correspond to the first sample in a distribution that comes from a resulting Monte Carlo generation. Therefore, Sample Set distributions in a chain of Monte Carlo generations are likely to all be correlated with each other. This connection breaks if any node changes to the Point Set or Symbolic format.
In this example, we subtract all three types of distributions by themselves. Notice that the Sample Set distribution returns 1. The other two return the result of subtracting one normal distribution from a separate uncorrelated distribution. These results are clearly very different to each other.
<SquiggleEditor
defaultCode={`sampleSetDist = normal(5,2) |> SampleSet.fromDist
sampleSetDistToPointSet = sampleSetDist |> PointSet.fromDist
symbolicDist = normal(5,2)

In our docusaurus repo, we have a static asset called `demo.squiggle`. It looks like this
```js
x = 1 to 2
y = {a: x, b: 1e1}
f(t) = normal(t, 1.1)
z = y.b * y.a
```
We can call `f(z)` upon the assignments in `demo.squiggle` like so:
```jsx
import { SquiggleEditorWithImportedBindings } from "../../src/components/SquiggleEditor";
<SquiggleEditorWithImportedBindings
defaultCode={"f(z)"}

/>;
```
Notice, you need to wrap the export of `@quri/squiggle-components` in custom code for dynamicism, please view `packages/website/src/components/` in github for details.

title: Overview

import { SquiggleEditor } from "../src/components/SquiggleEditor";
Squiggle is a minimalist programming language for probabilistic estimation. It's meant for intuitively-driven quantitative estimation instead of data analysis or data-driven statistical techniques.
The basics of Squiggle are fairly straightforward. This can be enough for many models. The more advanced functionality can take some time to learn.
## Simple example
Say you're trying to estimate the number of piano tuners in New York City. You can build a simple model of this, like so.
(Tip: This is interactive! Feel free to modify the code directly.)
<SquiggleEditor
defaultCode={`
// Piano tuners in NYC over the next 5 years
populationOfNewYork2022 = 8.1M to 8.4M // This means that you're 90% confident the value is between 8.1 and 8.4 Million.\n
proportionOfPopulationWithPianos = {
percentage = (.2 to 1)
percentage * 0.01
} // We assume there are almost no people with multiple pianos\n
pianoTunersPerPiano = {
pianosPerPianoTuner = 2k to 50k // This is artificially narrow, to help graphics later
1 / pianosPerPianoTuner
} \n
totalTunersIn2022 = populationOfNewYork2022 * proportionOfPopulationWithPianos * pianoTunersPerPiano
totalTunersIn2022
`}
/>
---
Now let's take this a bit further. Let's imagine that you think that NYC will grow over time, and you'd like to estimate the number of piano tuners for every point in time for the next few years.
<SquiggleEditor
defaultCode={`// Piano tuners in NYC over the next 5 years
populationOfNewYork2022 = 8.1M to 8.4M\n
proportionOfPopulationWithPianos = {
percentage = (.2 to 1)
percentage * 0.01
} // We assume there are almost no people with multiple pianos\n
pianoTunersPerPiano = {
pianosPerPianoTuner = 2k to 50k // This is artificially narrow, to help graphics later
1 / pianosPerPianoTuner
} \n
//Time in years after 2022
populationAtTime(t) = {
averageYearlyPercentageChange = -0.01 to 0.05 // We're expecting NYC to continuously grow with an mean of roughly between -1% and +4% per year
populationOfNewYork2022 * ((averageYearlyPercentageChange + 1) ^ t)
}\n
median(v) = quantile(v, .5)
totalTunersAtTime(t) = populationAtTime(t) * proportionOfPopulationWithPianos * pianoTunersPerPiano\n
{
populationAtTime: populationAtTime,
totalTunersAtTimeMedian: {|t| median(totalTunersAtTime(t))}
}`}
/>
If you haven't noticed yet, you can hover over the `populationAtTime` graph to see the distribution of population at different points in time.
## Using Squiggle
You can currently interact with Squiggle in a few ways:
**[Playground](/playground)**
The [Squiggle Playground](/playground) is a nice tool for working with small models and making prototypes. You can make simple shareable links, but you can't save models that change over time.
**[Visual Studio Code Extension](https://marketplace.visualstudio.com/items?itemName=QURI.vscode-squiggle)**
There's a simple [VS Code extension](https://marketplace.visualstudio.com/items?itemName=QURI.vscode-squiggle) for running and visualizing Squiggle code. We find that VS Code is a useful editor for managing larger Squiggle setups.

Squiggle is built using [Rescript](https://rescript-lang.org/), and is accessible via a simple Typescript library. You can use this library to either run Squiggle code in full, or to call select specific functions within Squiggle (though this latter functionality is very minimal).
**[React Components Library](https://www.npmjs.com/package/@quri/squiggle-components)**
All of the components used in the playground and documentation are available in a separate component NPM repo. You can see the full Storybook of components [here](https://squiggle-components.netlify.app).
**[Observable](https://observablehq.com/@hazelfire/squiggle)**
You can use Squiggle Components in Observable notebooks. Sam Nolan put together an exportable [Observable Notebook](https://observablehq.com/@hazelfire/squiggle) of the key components that you can directly import and use in your Observable notebooks.
## Squiggle Vs. Other Tools
### What Squiggle Is
- A simple programming language for doing math with probability distributions.
- An embeddable language that can be used in Javascript applications.
- A tool to encode functions as forecasts that can be embedded in other applications.
### What Squiggle Is Not
- A complete replacement for enterprise Risk Analysis tools. (See [Crystal Ball](https://www.oracle.com/applications/crystalball/), [@Risk](https://www.palisade.com/risk/), [Lumina Analytica](https://lumina.com/))
- A [probabilistic programming language](https://en.wikipedia.org/wiki/Probabilistic_programming). Squiggle does not support Bayesian inference.
- A tool for substantial data analysis. (See programming languages like [Python](https://www.python.org/) or [Julia](https://julialang.org/))
- A programming language for anything other than estimation.
- A visually-driven tool. (See [Guesstimate](https://www.getguesstimate.com/) and [Causal](https://causal.app/))
### Strengths
- Simple and readable syntax, especially for dealing with probabilistic math.
- Fast for relatively small models. Strong for rapid prototyping.
- Optimized for using some numeric and symbolic approaches, not just Monte Carlo.
- Embeddable in Javascript.
- Free and open-source.
### Weaknesses
- Limited scientific capabilities.
- Much slower than serious probabilistic programming languages on sizeable models.
- Can't do Bayesian backwards inference.
- Essentially no support for libraries or modules (yet).
- Still very new, so a tiny ecosystem.
- Still very new, so there are likely math bugs.
- Generally not as easy to use as Guesstimate or Causal, especially for non programmers.
## Organization
Squiggle is one of the main projects of [The Quantified Uncertainty Research Institute](https://quantifieduncertainty.org/). QURI is a nonprofit funded primarily by [Effective Altruist](https://www.effectivealtruism.org/) donors.
