JavaFit: A platform independent program for interactive nonlinear least-squares fitting using the Levenberg—Marquardt method Original Research Article

The JavaFit program is a package for carrying out interactive nonlinear least-squares fitting to determine the parameters of physical models from experimental data. It has been conceived as a platform independent package aimed at the relatively modest computational needs of spectroscopists, where it is often necessary to determine physical parameters from a variety of spectral lineshape models. The program is platform independent, provided that a Java runtime module is available for the host platform. The program is also designed to read a wide variety of data in ASCII column formats produced on DOS, Macintosh and UNIX platforms.
