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.
