I developed a new risk analysis tool called Statscorer which allows do to Monte Carlo simulations within Excel and in-depth stochastic modeling, while remaining very simple.

I will be interested to know your opinion since it’s a bit different from its competitors: you can correlate directly input variables with formal expression (e.g.: X3=Exp(X1)+ln(X2^2+1), …), export raw data in a text file and other stuffs.

You can download a 15-day evaluation version freely (no personal information required).
Also I will give a free 3-month subscription to the readers of finance 3.0 (this offer runs until march 2011). Just send me an email to support@statscorer.com mentioning you are a reader of Finance 3.0

You can visit http://www.statscorer.com to get many detailed examples of how to create stochastic models in Excel with Statscorer. Finally, I will be glad to help you to define your finest financial model.

Thanks!
