Ersatz was originally developed as a low-cost alternative to @Risk and Crystal Ball. The Ersatz program has
additional features included for users who are interested in health economic evaluation modeling and/or microsimulation using Excel.
Ersatz makes more than 80 additional functions available in Excel, most of them producing randomly drawn numbers from
specific distributions, but also output, control, statistical, and special functions to calculate such things as health-adjusted discounted life years. The software comes with several example
spreadsheets that will give you an excellent idea of Ersatz’s power, versatility, and simplicity of use.
The full version of Ersatz was formerly sold for a small fee. This software has now been made freely
