SimFit simulation and statistics program

Simfit is a computer package for simulation, It is collection of Macros and is packaged with a GUI to access its functionality. It is freeware and advertises that it leaves no registry entries. It is good for teaching and data analysis and has decent plotting and graph creation capabilities. It seems like a natural for supplementing the education and/or office functionality of PortableApps;
