BioDataFit is a data fitting program specifically designed for
biologists. It can be used to model dose-response, ligand-binding,
enzyme kinetics, and growth inhibition. Includes
four-parameter/sigmoidial model for calculating EC50 (IC50, DC50,
GI50) values.  A good tool for teaching as well as for research.

Please let me know if you would like to add another model. Thanks.
