Simfit is a computer package for simulation, statistical analysis, curve fitting and graph plotting using models from a compiled library or from ASCII text files supplied by the user. It can be used for teaching the principles of curve fitting, simulation and statistical analysis to students, but it will be found most useful by those interested in serious data analysis and creating professional, publication quality scientific graphs
