Hi, Wow lots of maths lol, though I did quantative maths several times at college and uni (and passed) I hated it lol, I would much rather let a computer do the hard work. Don’t get me wrong, I still study statistics and managerial economics but I translate the problems onto my computer rather than do them by hand. Guess I am more inclined to use the creative side of the brain.
Anyway, the reason for this response is a nice little freebie called MicrOsiris in my opinion its not as intuitive as @Risk or Crystal Ball and not as easy to use but with some practice it is well worth downloading.
NOTE - IT IS NOT SO GOOD FOR OLDER SLOWER COMPUTERS AS IT USES A LOT OF CAPACITY.
I copied this from their information.
Management Software (Freeware)
Version 14 2/5/2011
MicrOsiris is a comprehensive statistical and data management package for Windows developed by Van Eck Computer Consulting and freely distributed. Derived from OSIRIS IV, a statistical and data management package developed and used at the University of Michigan, MicrOsiris includes special techniques for data mining (SEARCH) and analysis of nominal- and ordinal-scaled data (MNA, MCA) and an interface to IVEware.
The MicrOsiris IVEware interface command, IVEWARE, invokes the Srcware version of IVEware (installed with MicrOsiris) that can:
- Perform single or multiple imputations of missing values using the Sequential Regression Imputation Method.
- Perform a variety of descriptive and model based analyses accounting for such complex design features as clustering, stratification and weighting.
- Perform multiple imputation analyses for both descriptive and model-based survey statistics.
- Returns an imputed data set for further analysis in MicrOsiris.
MicrOsiris accepts data from SPSS, SAS, STATA, and Excel as well as from other sources, including UNESCO IDAMS datasets and older OSIRIS datasets from ICPSR.
It will run under a Windows virtual machine on a Mac and on Ubunto/Linux under Wine.

The Decision Tree for Statistics (Freeware; included with MicrOsiris or use link below).
The Decision Tree helps select statistics or statistical techniques appropriate for the purpose and conditions of a particular analysis and to select the MicrOsiris commands, which produce them or find the corresponding SPSS and SAS commands.
Hope this is useful to you guys.
