MacMCMC (v1.2)
State-of-the-art Data Analysis for MacOS™
MacMCMC is a free and extremely powerful application for the analysis of data of any kind. It is one half of a two-part project. The other half is a free ebook—a strongly recommended preliminary—available here.
To see MacMCMC in action, consider this famous example from the literature (Arnold and Libby, 1949):
Carbon-14 Dating
MacMCMC does not plot equations but, given its report, anyone can readily do that.
Note: The blue line in this plot uses mean estimates; the red line is the prior uncertainty for parameter A.
