Nonlinear regression analysis - CurveFitter Regression Analysis - CurveFitter 4.5.8 CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called curve fitting.

Works great. Quickly fit an accurate equation in 4 variables for me.

Review of curve fit. Excellent software. Can be improved by introducing more functions.

Not appropriate for my needs I needed a piecewise quintic or cubic regression and this is not supported (at least easily)

NLREG performs nonlinear regression NLREG 6.2 NLREG performs nonlinear regression and curve fitting. NLREG fits a mathematical function whose form you specify to a set of data values. Virtually any type of function can be fitted. NLREG includes a programming language similar to C that you use for describing the function to be fitted. Two dimensional line and three dimensional surface plots can be generated.

I bought it. Sort of says it all ...
