Squiggle is a special-purpose coding language for generating  probability distributions, estimates of variables over time, and similar tasks. It was developed by the Quantified Uncertainty Research Institute.

Tutorials

The official basics guide is a good written guide if you have experience programming and/or have a specific project in mind already. 

There’s also a few simple worked  examples to demonstrate squiggle’s value, and a more complex model based on GiveWell's cost effectiveness analyses. Note that squiggle is still in development and has several known bugs.
