Simulating Inexact Spreadsheet Numbers

A free, open source package called Guesstimate was just brought to my attention.  In Beta.  Overview article here.  Essentially a means for modeling uncertain values in your models.  We used a similar, commercial approach that I assume is still out there.   Nice idea, but does require considerable statistical assumptions about distributions that can be important.   This is a standalone 'spreadsheet', rather than a spreadsheet add-on, which can also be a problem for existing business use.   Try it here.  Similar things can be done with commercial packages like SPSS and SAS.
