In 1999 Simo Särkkä implemented several Markov chain Monte Carlo (MCMC) convergence diagnostics in Matlab at Laboratory of Computational Engineering. Later Aki Vehtari added additonal functions, fixed bugs and improved the documentation.

- 2014-02-24: psrf.m and cpsrf.m use now the new method for computing the potential scale reduction as described in Bayesian Data Analysis, Third Edition. Chapman and Hall/CRC. Publisher's webpage for the book.
- 2004-01-23: Added computation of effective number of samples and changed returned R to square-root definition in psrf.m, cpsrf.m, mpsrf.m, cmpsrf.m. Created new functions ipsrf.m and cipsrf.m implementing interval-based PSRF.
- 2003-11-04: Added geyer_imse.m for those who do not have Optimization toolbox.
