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. The programming language includes a large selection of built-in library functions (sin, cos, log, exp, etc.) that makes it easy to describe complicated models.
DMFitter ActiveX control DMFitter ActiveX control allows you to add sophisticated regression analysis tools to your software in a few lines of code. Both linear and nonlinear (Levenberg-Marquardt) least squares curve fitting algorithms with user defined models are available.
Regression Analysis - CurveFitter CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions.
DataFit DataFit is a tool for performing 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.
