Auto2Fit is a revolution tools and beats all other simliar ones in the area of nonlinear regression!Almost all data analysis software packages (SPSS, SAS, Statistical,Origin Pro, DataFit, Stata or Systat) need end-users to provide/guessinitial start values, and the successes of nonlinear regression computation are havily depended on those guessed data...With the unique, robust and high efficient optimation algorithms of "Global Levenberg-Marquardt" and "Global BFGS", proposed newly,Auto2Fit is no long to require the end-users to provide/guess initial start values (but with free random ones), the performance, however, ismuch better than any others...Auto2Fit is also a flexible, versatile, easiest-to-use tool in the areas of function optimization, equation solving, parameter estimation,combinational problems (like TSP) and chart drawing...
