dtstudent: Discrete Truncated Student-t Distribution for R

Matthew Kay, University of Michigan [e-mail]

This is a package implementing a discrete, truncated Student-t distribution, which I have found useful in robustly modeling people's responses on rating scales, or even as an alternative to a Beta distribution in modeling people's estimates of probabilities in visualizations.

It includes the customary [dpqr]dtstudent() functions, and also (somewhat hackishly) defines support for the discrete truncated Student-t distribution for use with the map2stan function in Richard McElreath's rethinking package.

Installation

You can install the latest development version from GitHub with these R commands:

install.packages("devtools")
devtools::install_github("mjskay/dtstudent")

Example

TBD

Example with rethinking package
