Arriving in my mail, on May 9, `996, was an upgrade announcement for @RISK. This is a popular spreadsheet add-in for doing Monte Carlo simulation.
@RISK provides three general capabilities for the spreadsheet modeler:
1. Thirty-seven distribution functions, including the new PERT and Beta Subjective, are provided for sampling random variables (i.e., probability distributions).
2. The spreadsheet is surrounded by a control shell that provides for executing the trial iterations, saving output values, and monitoring execution.
3. Data summarization and graphics routines are provided to analyze and display the run results.
@RISK 3.5 uses the 32-bit architecture of Windows 95. Palisade claims this results in improved stability and performance (I'll find out). Additionally, the new version handles larger models.

@RISK and its chief competitor, Crystal Ball , are both excellent tools for Monte Carlo simulation when the underlying business model is in a spreadsheet.
