FitAll

FitAll , is a nonlinear (& linear) regression analysis (curve fitting) tool that can help you to extract meaningful results from your data. The conventional wisdom has been that you must transform the model (equation) that describes your system so that it can be fit using linear regression analysis. With FitAll this is not necessary -- you can fit your data to the model that actually describes it. In addition to creating and selling FitAll , MTR Software provides value added consulting services that include, but are not limited to, creating custom FitAll Function Libraries.
