gfit is a program for global (simultaneous) regression analysis of data from different types of experiments. It is particularly useful for studying various systems in Biophysics, Biochemistry and Cell Biology. With gfit one can create a model for virtually any type of system using minimal amount of computer code. The interface between models and data is rule-based. It allows models to be re-used for many related problems.

Using gfit one can globally fit many experiments to a suitable model of your system. gfit was designed for difficult cases of data analysis. Use gfit to globally analyze experiments of different types, to implement complex models (any algorithm can be used), to apply statistical weights to measured data, etc.
