Latest Update: Version 14.1 (May 1, 2025)
Users of BestCurvFit are encouraged to download the latest version of BestCurvFit. Users with an active license can download and activate the software with their current activation code. If anyone encounters an issue with BestCurvFit, please let us know via our email (DrFrank88@gmail.com).
BestCurvFit performs nonlinear regression curve-fitting of data to kinetic models either defined by the user or selected from in internal library of 46 models. BestCurvFit is priced to make it affordable to professionals and students alike. But don't let the low price mislead you. BestCurvFit is robust and powerful using some of the most sophisticated regression algorithms, including Variable Metric, Gauss-Newton as modified by Marquardt-Levenberg , Conjugate Gradient, Hooke-Reeves, and Random search methods. Why pay hundreds and yearly license fees when you can have curve-fitting software for a fraction of the cost. Best of all, there are no time limit restrictions or number of uses.
With just one-click of the mouse, BestCurvFit simplifies curve fitting your data to mathematical models. Select an equation from an internal library of 46 models or enter your own function, and BestCurvFit does the rest by fitting the curve to your data set, displaying the statistical results, model parameters, the best fit curve, and the residuals.
The BestCurvFit results of your curve-fit includes the fitted parameters, their standard errors, their significance , confidence limits, correlation matrix, and measures of parameter redundancy like variance decomposition proportions and condition index, and eigenvalues and principle component values.
An important measure of a good curve-fit is the residuals plot. BestCurvFIt includes statistic tests for the residuals plot. These tests include (1) Distribution-free Runs statistic test of the randomness of residuals, (2) F-test statistic to determines if the mean of the residuals is significantly different than zero, (3) Durbin-Watson statistic test of residuals to determine if a serial correlation exists, (4) Kolmogorov-Smirnov non-parametric, distribution-free, statistic test of residuals to determine whether positive and negative residuals come from the same distribution, (5) Hotelling's T-squared distribution (T²) multivariate statistic used to measure dissimilarity for outlier detection in the data set, and (6) Besseli0 function of residuals to detect outlying data.
