![]() A number of optimization algorithms have been integrated in Auto2Fit:.Chart Drawing: 2-D, 3-D cartesian and 2-D parametric function chart, especial for implicit functions.Combinational Problems: solve problems like TSP and Short-Path.Model Auto-calibration: parameter estimation of complicated engineering model.Equation Solve: solve any type of equation or system equations, both linear and nonlinear.The function may be nonlinear, non-continues, non derivable. Global Optimization: find the maximal/minimal value of any function.Regression and Curve Fit: linear, nonlinear, multi-nonlinear with no limitations on variable and parameter number.Auto2Fit can be used in the areas such as:.Auto2Fit has turned to be the best one for nonlinear regerssion analysis nowadays.Īuto2Fit 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. ![]() 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, is much better than any others. Unfortunately, for most of people, the guesses of proper start values are nightmare. Commercial New DescriptionĪuto2Fit is a revolution tools and beats all other simliar ones in the area of nonlinear regression.Īlmost all data analysis software packages (SPSS, SAS, Statistical, Origin Pro, DataFit, Stata or Systat) need end-users to provide/guess initial start values, and the successes of nonlinear regression computation are havily depended on those guessed data. ![]()
