Merge branch 'develop' into vscode
* develop: fix SquigglePlayground in storybook Ran formatter Added scaleMultiply to docs Added scaleMultiply useSquiggle and useSquigglePartial hooks v0.2.11 fix: Make lodash a dependency, rather than a dev dependency Ran formatting Normalize after trunctae Ran formatter Added descriptions to last API types Fixed link that was breaking build Small edits to guides section More progress on DistGeneric Ran format Added key math variables, all lowercase Removed the definitions tags in documentation Minor cleanup on distributions Lots of documentation tweaks

Squiggle dictionaries work similar to Python dictionaries. The syntax is similar to objects in Javascript.
|
||||
|
||||
Dictionaries are unordered and duplicates are not allowed. They are meant to be immutable, like most types in Squiggle.

||||
|
||||

||||

Distributions are the flagship data type in Squiggle. The distribution type is a generic data type that contains one of three different formats of distributions.
|
||||
These subtypes are [point set](/docs/Api/DistPointSet), [sample set](/docs/Api/DistSampleSet), and symbolic. The first two of these have a few custom functions that only work on them. You can read more about the differences between these formats [here](/docs/Discussions/Three-Formats-Of-Distributions).
|
||||
|
||||
Several functions below only can work on particular distribution formats.
|
||||
For example, scoring and pointwise math requires the point set format. When this happens, the types are automatically converted to the correct format. These conversions are lossy.

## Distribution Creation
|
||||
|
||||
### Normal Distribution
|
||||
These are functions for creating primative distributions. Many of these could optionally take in distributions as inputs. In these cases, Monte Carlo Sampling will be used to generate the greater distribution. This can be used for simple hierarchical models.
|
||||
|
||||
**Definitions**
|
||||
See a longer tutorial on creating distributions [here](/docs/Guides/DistributionCreation).
|
||||

||||

### to / credibleIntervalToDistribution
|
||||
|
||||
The `to` function is an easy way to generate simple distributions using predicted _5th_ and _95th_ percentiles.
|
||||
|
||||
If both values are above zero, a `lognormal` distribution is used. If not, a `normal` distribution is used.
|
||||
|
||||
`To` is an alias for `credibleIntervalToDistribution`. However, because of its frequent use, it is recommended to use the shorter name.

||||

||||

## Normalization
|
||||
|
||||
There are some situations where computation will return unnormalized distributions. This means that their cumulative sums are not equal to 1.0. Unnormalized distributions are not valid for many relevant functions; for example, klDivergence and scoring.
|
||||
|
||||
The only functions that do not return normalized distributions are the pointwise arithmetic operations and the scalewise arithmetic operations. If you use these functions, it is recommended that you consider normalizing the resulting distributions.
|
||||
|
||||
### normalize
|
||||
|
||||

||||

## Algebraic Operations

## Regular Arithmetic Operations
|
||||
|
||||
Regular arithmetic operations cover the basic mathematical operations on distributions. They work much like their equivalent operations on numbers.
|
||||
|
||||
The infixes `+`,`-`, `*`, `/`, `^` are supported for addition, subtraction, multiplication, division, power, and unaryMinus.
|
||||
|

|

## Pointwise Arithmetic Operations
|
||||
|
||||
<Admonition type="caution" title="Unnormalized Results">
|
||||
<p>
|
||||
Pointwise arithmetic operations typically return unnormalized or completely
|
||||
invalid distributions. For example, the operation{" "}
|
||||
<code>normal(5,2) .- uniform(10,12)</code> results in a distribution-like
|
||||
object with negative probability mass.
|
||||
</p>
|
||||
</Admonition>
|
||||
|
||||
Pointwise arithmetic operations cover the standard arithmetic operations, but work in a different way than the regular operations. These operate on the y-values of the distributions instead of the x-values. A pointwise addition would add the y-values of two distributions.

Scale operations are similar to pointwise operations, but operate on a constant y-value instead of y-values coming from a distribution. You can think about this as scaling a distribution vertically by a constant.
|
||||
|
||||
The following items would be equivalent.
|
||||
|

```js
|

scalePow(normal(5,2), 2)

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.
|
||||
|
||||
### make
|
||||
|
||||
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.

Sample set distributions are one of the three distribution formats. Internally, they are stored as a list of numbers. It's useful to distinguish point set distributions from arbitrary lists of numbers to make it clear which functions are applicable.
|
||||
|
||||
Monte Carlo calculations typically result in sample set distributions.

`delta(value:number)`

`pointMass(value:number)`
|

|

Creates a discrete distribution with all of its probability mass at point `value`.

|

Few Squiggle users call the function `delta()` directly. Numbers are converted into delta distributions automatically, when it is appropriate.

Few Squiggle users call the function `pointMass()` directly. Numbers are converted into point mass distributions automatically, when it is appropriate.
|
||||
|
||||
For example, in the function `mixture(1,2,normal(5,2))`, the first two arguments will get converted into delta distributions
|
||||
with values at 1 and 2. Therefore, this is the same as `mixture(delta(1),delta(2),normal(5,2))`.

We can now look at the inverse cdf of a $Normal(0,1)$. We find that the 95% point is reached at $1.6448536269514722$. ([source](https://stackoverflow.com/questions/20626994/how-to-calculate-the-inverse-of-the-normal-cumulative-distribution-function-in-p)) This means that the 90% confidence interval is $[-1.6448536269514722, 1.6448536269514722]$, which has a width of $2 \cdot 1.6448536269514722$.

|

|

So then, if we take a $Normal(0,1)$ and we multiply it by $\frac{(high -. low)}{(2. *. 1.6448536269514722)}$, it's 90% confidence interval will be multiplied by the same amount. Then we just have to shift it by the mean to get our target normal.
