DMFitter ActiveX control allows you to add sophisticated regression analysis tools to your software in a few lines of code. Features include: both linear and nonlinear (Levenberg-Marquardt) least squares curve fitting algorithms, arbitrary user models (defined analytically or by string expressions), event support, weighting. Examples for Excel, VB, Delphi, MSIE, Data Master 2003 and scripting languages are included.

DataFitting is a powerful statistical analysis program that performs linear and nonlinear regression analysis (i.e. curve fitting). DataFitting determines the values of parameters for an equation, whose form you specify, that cause the equation to best fit a set of data values.

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.

QuickFit Suite is a 32 bit software product that consists of 2 programs - 1. QuickFit performs a polynomial least squares fit (up to ninth order) on user-entered data. 2. QuickMVR performs a multivariable regression on user entered-data.
