NLREG
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.

TriLookup Mac
Excel add-in with eleven powerful worksheet functions for 1, 2 and 3 variable lookup and interpolation. Interpolation modes include: closest-value, linear, piecewise parabolic or hyperbolic, cubic spline and polynomial up to 20th order. Handles tables with missing data.
Fits polynomial curves through a set of X-Y points, returns table of polynomial coefficients and finds the best fit curve.
Includes online help and examples for Windows and Mac.

LAB Fit Curve Fitting Software
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).
