NLREG
by Phillip H. Sherrod
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.

LAB Fit Curve Fitting Software
by Wilton Pereira da Silva
The LAB Fit is a software for Windows developed for treatment and analysis of experimental data. At LABFit you are able to:
1) Treat similar data;
2) Treat non-similar data;
3) Determine propagated error;
4) Plot 2D and 3D graphs;
5) Execute math calculations (system of equations, roots of function, etc);
6) Curve Fit (almost 500 functions at the library, with 1 and 2 independent
variables, functions finder, rejection of data).

Regression analysis - CurveFitter
by Institute of Mathematics and Statistics
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.
