The YASAI.XLA add-in was designed for teaching elementary Monte Carlo simulation in Microsoft Excel. Although numerous similar tools do already exist, we needed one that was simple to use for mathematically unsophisticated beginning students, and could be used and installed easily without system administrator privileges. Please read the online journal article or the RRR report for a detailed description of the reason we developed YASAI and our design philosophy.
'Yasai' also means 'vegetables' in Japanese.
