[WSD test]

Here you can find the R-script of the Bayesian WinBUGS Savage Dickey (WSD) t-test. This test is inspired by Rouder et al.'s JZS t-test. The script is working correctly, but I'm still working on more user-friendly output options such as plots or lists.

Get the R-script here: WSD test.

Get Dr. Smith's data .

Get the file to examine Dr. Smith's data (wsd_work.r) here.

[The programs]

The WSD test is written in R. R is a language and environment for statistical computing and graphics, and comes free of charge. However, to run the test, you also need WinBUGS. This program is also freely available and is used for Gibbs Sampling (BUGS stands for Bayesian inference Using Gibbs Sampling).

Get R here. You need to install the package R2WinBUGS.

Get WinBUGS here. Don't forget the register code, WinBUGS won't work without it.

[Some explanation]

Here is a very short explanation of how to get everything to work. I hope to have a more detailed explanation of how to get everything to work online soon. For a more technical review of the test, you can also read the article .
