R2mim {SAGx} | R Documentation |
Given a candidate probe, it produces a script file for WinMIM by calculating means and covariances and for the N most highly correlated probes (in absolute value). Here N is an input parameter, but a recommended value 10. WinMIM can find a relevant graphical model for the dependencies between the probes.

David Edwards' program WinMIM can be found on
StatLib (http://lib.stat.cmu.edu/graphmod/). In MIM issue input mimscr.txt
and the calculations to find a model will start. When finished go to the Graphics menu and
click on Independence Graph
. The resulting graph can be exported both to WMF and LaTeX.
