Reed, Depending on how good you are at statistics, there is a matrix algebra cfc on the Adobe CF Exchange (http://www.antiwrap.com/?1022) that you can use to construct most advanced stats equations, such as various regressions, GLM equations etc. In my own stats related site on meta-analysis (http://www.antiwrap.com/?1023) I mostly use CF's built in functions (ArraySum, ArrayAverage) to perform the analysis. Another very good resource is CFLib.org. There's a section of the maths library that has quite f few stats related UDFs that you can integrate into your app. http://www.cflib.org/library.cfm?ID=6 Finally there's an open source regression CFC at CFCZone.org. hth, larry -- Larry C.
