#### Validity

- `low < high`

### Lognormal distribution
|
||||
|
||||
The `lognormal(mu, sigma)` returns the log of a normal distribution with parameters
|
||||
mu and sigma. The log of lognormal(mu, sigma) is a normal distribution with parameters
|

mean mu and standard deviation sigma.

#### Future feature:
|
||||
|

Furthermore, it's also possible to create a lognormal from it's actual mean
|
||||
and standard deviation, using `lognormalFromMeanAndStdDev`.

<SquiggleEditor initialSquiggleString="lognormalFromMeanAndStdDev(20, 10)" />
|
||||
|
||||
#### Validity
|
||||
|
||||
- `sigma > 0`
|
||||
- In `x to y` notation, `x < y`
|
||||
|
||||
### Beta distribution
|
||||
|
||||
The `beta(a, b)` function creates a beta distribution with parameters a and b:
|
||||
The `beta(a, b)` function creates a beta distribution with parameters `a` and `b`:
|
||||
|
||||
<SquiggleEditor initialSquiggleString="beta(20, 20)" />
|
||||
<SquiggleEditor initialSquiggleString="beta(10, 20)" />
|
||||
|
||||
#### Validity
|
||||
|
||||
- `a > 0`
|
||||
- `b > 0`
|
||||
- Empirically, we have noticed that numerical instability arises when `a < 1` or `b < 1`
|
||||
|
||||
### Exponential distribution
|
||||
|
||||
The `exponential(mean)` function creates an exponential distribution with the given
|
||||
mean.
|
||||
The `exponential(rate)` function creates an exponential distribution with the given
|
||||
rate.
|
||||
|
||||

|
||||
<SquiggleEditor initialSquiggleString="exponential(1.11)" />
|
||||
|
||||
### The Triangular distribution
|
||||
#### Validity
|
||||
|
||||
- `rate > 0`
|
||||
|
||||
### Triangular distribution
|
||||
|
||||
The `triangular(a,b,c)` function creates a triangular distribution with lower
|
||||
bound a, mode b and upper bound c.
|
||||
bound `a`, mode `b` and upper bound `c`.
|
||||
|
||||
#### Validity

||||
|
||||
- `a < b < c`

||||
|
||||
<SquiggleEditor initialSquiggleString="triangular(1, 2, 4)" />

||||
|
||||
### Multimodal distriutions
|
||||
### Scalar (constant dist)
|
||||
|
||||
The multimodal function combines 2 or more other distributions to create a weighted
|
||||
Squiggle, when the context is right, automatically casts a float to a constant distribution.
|
||||
|
||||
## Operating on distributions
|
||||
|
||||
Here are the ways we combine distributions.
|
||||
|
||||
### Mixture of distributions
|
||||
|
||||
The `mixture` function combines 2 or more other distributions to create a weighted
|
||||
combination of the two. The first positional arguments represent the distributions
|
||||
to be combined, and the last argument is how much to weigh every distribution in the
|
||||
combination.
|
||||
|
||||
<SquiggleEditor initialSquiggleString="mx(uniform(0,1), normal(1,1), [0.5, 0.5])" />
|
||||
<SquiggleEditor initialSquiggleString="mixture(uniform(0,1), normal(1,1), [0.5, 0.5])" />
|
||||
|
||||
It's possible to create discrete distributions using this method.
|
||||
|
||||
<SquiggleEditor initialSquiggleString="mx(0, 1, [0.2,0.8])" />
|
||||
<SquiggleEditor initialSquiggleString="mixture(0, 1, [0.2,0.8])" />
|
||||
|
||||
As well as mixed distributions:
|
||||
|
||||
<SquiggleEditor initialSquiggleString="mx(3, 8, 1 to 10, [0.2, 0.3, 0.5])" />
|
||||
<SquiggleEditor initialSquiggleString="mixture(3, 8, 1 to 10, [0.2, 0.3, 0.5])" />
|
||||
|
||||
## Other Functions
|
||||
An alias of `mixture` is `mx`
|
||||
|
||||
### PDF of a distribution

||||
#### Validity

||||
|
||||

||||
Using javascript's variable arguments notation, consider `mx(...dists, weights)`:
|
||||
|
||||
- `dists.length == weights.length`

### Addition

|
||||
initialSquiggleString={`x = 2
|
||||
dist = beta(2,3)
|
||||
log(dist, x)`}
|
||||
/>
|
||||
|
||||
#### Validity
|
||||
|
||||
- `x` must be a scalar

## Standard functions on distributions
|
||||
|
||||
### Probability density function
|
||||
|
||||
The `pdf(dist, x)` function returns the density of a distribution at the
|
||||
given point x.
|
||||
|
||||
<SquiggleEditor initialSquiggleString="pdf(normal(0,1),0)" />
|
||||
|
||||
### Inverse of a distribution
|
||||
#### Validity
|
||||
|
||||
The `inv(distribution, prob)` gives the value x or which the probability for all values
|
||||
lower than x is equal to prob. It is the inverse of `cdf`.
|
||||
- `x` must be a scalar
|
||||
- `dist` must be a distribution
|
||||
|
||||
<SquiggleEditor initialSquiggleString="inv(normal(0,1),0.5)" />
|
||||
### Cumulative density function
|
||||
|
||||
### CDF of a distribution
|
||||
|
||||
The `cdf(distribution,x)` gives the cumulative probability of the distribution
|
||||
The `cdf(dist, x)` gives the cumulative probability of the distribution
|
||||
or all values lower than x. It is the inverse of `inv`.
|
||||
|
||||
<SquiggleEditor initialSquiggleString="cdf(normal(0,1),0)" />
|
||||
|
||||
### Mean of a distribution
|
||||
#### Validity
|
||||
|
||||
- `x` must be a scalar
|
||||
- `dist` must be a distribution
|
||||
|
||||
### Inverse CDF
|
||||
|
||||
The `inv(dist, prob)` gives the value x or which the probability for all values
|
||||
lower than x is equal to prob. It is the inverse of `cdf`.
|
||||
|
||||
<SquiggleEditor initialSquiggleString="inv(normal(0,1),0.5)" />
|
||||
|
||||
#### Validity
|
||||
|
||||
- `prob` must be a scalar (please only put it in `(0,1)`)
|
||||
- `dist` must be a distribution
|
||||
|
||||
### Mean
|
||||
|
||||
The `mean(distribution)` function gives the mean (expected value) of a distribution.

|

The `sample(distribution)` samples a given distribution.

<SquiggleEditor initialSquiggleString="sample(normal(0, 10))" />
|
||||
|
||||
## Normalization
|
||||
|
||||
Some distribution operations (like horizontal shift) return an unnormalized distriibution.
|
||||
|
||||
We provide a `normalize` function
|
||||
|
||||
<SquiggleEditor initialSquiggleString="normalize((0.1 to 1) + triangular(0.1, 1, 10))" />
|
||||
|
||||
#### Validity - Input to `normalize` must be a dist
|
||||
|
||||
We provide a predicate `isNormalized`, for when we have simple control flow
|
||||
|
||||
<SquiggleEditor initialSquiggleString="isNormalized((0.1 to 1) * triangular(0.1, 1, 10))" />
|
||||
|
||||
#### Validity
|
||||
|
||||
- Input to `isNormalized` must be a dist
|
||||
|
||||
## Convert any distribution to a sample set distribution
|
||||
|
||||
`toSampleSet` has two signatures
|
||||
|
||||
It is unary when you use an internal hardcoded number of samples
|
||||
|
||||
<SquiggleEditor initialSquiggleString="toSampleSet(0.1 to 1)" />
|
||||
|
||||
And binary when you provide a number of samples (floored)
|
||||
|
||||
<SquiggleEditor initialSquiggleString="toSampleSet(0.1 to 1, 100)" />
|
||||
|
||||
## `inspect`
|
||||
|
||||
You may like to debug by right clicking your browser and using the _inspect_ functionality on the webpage, and viewing the _console_ tab. Then, wrap your squiggle output with `inspect` to log an internal representation.
|
||||
|
||||
<SquiggleEditor initialSquiggleString="inspect(toSampleSet(0.1 to 1, 100))" />
|
||||
|
||||
Save for a logging side effect, `inspect` does nothing to input and returns it.

abstract: This document outlines some properties about algebraic combinations of distributions. It is meant to facilitate property tests for [Squiggle](https://squiggle-language.com/), an estimation language for forecasters. So far, we are focusing on the means, the standard deviation and the shape of the pdfs.

Invariants to check with property tests.

## Algebraic combinations
|
||||
|
||||
The academic keyword to search for in relation to this document is "[algebra of random variables](https://wikiless.org/wiki/Algebra_of_random_variables?lang=en)". Squiggle doesn't yet support getting the standard deviation, denoted by $\sigma$, but such support could yet be added.

### Divisions
|
||||
#### Divisions
|
||||
|
||||
Divisions are tricky, and in general we don't have good expressions to characterize properties of ratios. In particular, the ratio of two normals is a Cauchy distribution, which doesn't have to have a mean.

### Probability density functions (pdfs)
|
||||
|
||||
Specifying the pdf of the sum/multiplication/... of distributions as a function of the pdfs of the individual arguments can still be done. But it requires integration. My sense is that this is still doable, and I (Nuño) provide some _pseudocode_ to do this.

- Provide definitions for the probability density function, exponential, inverse, log, etc.
