Very good DataFix is a tool very powerful.

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.

Nice help. It's a big help to those people having a hard time dealing with math calculation, with this calculator, it helps a lot.

Regression Analysis - CurveFitter 1.3
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.

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)

DataFit 8.2
DataFit is a tool used to perform nonlinear regression (curve fitting), statistical analysis & data plotting. Fit equations with up to 100 parameters to data with up to 20 independent variables. Define your own equations or choose from over 600 pre-defined equations. Results include customizable 2D/3D plots, as well as detailed fit information. Export code in BASIC or C to use an equation in a user written program. Easy to learn and use.

Good software It's overall a good software!
But still may require user friendly environment.
Anyway, I am satisfied with this.
Thanks
