You think that @Risk and Crystal Ball are seriously overpriced for what they offer? Exactly my idea. So I
wrote my own, which I now make generally available as a low cost alternative.
Rather whimsically called ‘Ersatz’, this software is a full strength alternative, with some extra
features thrown in for those of you who are into 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.
Give the free trial version a spin. It comes with several example spreadsheets that will give you an excellent
idea of Ersatz’s power, versatility, and simplicity of use.
It’s a steal for just 100 Aus dollars!
