This one actually works without running `yarn` at the monorepo level, but it doesn't hurt. You must at least run it at this package level We assume you ran `yarn` at monorepo level.
The website depends on `squiggle-lang`, which you have to build manually.
```sh ```sh
yarn cd ../squiggle-lang
yarn build
``` ```
This command generates static content into the `build` directory and can be served using any static contents hosting service. Generate static content, to the `build` directory.
```sh ```sh
yarn build yarn build
``` ```
Your local dev server is here, opening up a browser window. Open a local dev server
```sh ```sh
yarn start yarn start

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. abstract: This document outlines some properties about algebraic combinations of distributions.

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.
