stanTuneR

This code uses the algebra solver in Stan to find the parameters of a distribution that produce a desired tail behavior. This can be a useful tool when choosing parameters for prior distributions. Here’s how to use it:

1. Choose a distribution.
2. Define the quantile boundaries and the amount of probability density that you wish to have above and below those boundaries.
3. Let Stan go find the parameters that produce the desired distribution.

Currently supported distributions:

•  Normal
•  Log-Normal
•  Beta
•  Gamma
•  Inverse Gamma
