CurveFitter

CurveFitter, developed by the Institute of Mathematics and Statistics, is a powerful tool in the field of statistical regression analysis. The latest version, 4.5.64, has significantly advanced capabilities for fitting linear, multivariate, polynomial, exponential, and nonlinear functions to your data. By estimating the values of the parameters that cause the function to best fit the observed data, CurveFitter excels in performing statistical regression analysis and understanding complex datasets.

The software, sized at just 1.3 MB, is efficient and compact, making it easy to download. Supported on a wide range of operating systems, including Windows XP, Vista, 7, 8, 10, and 11, CurveFitter offers flexibility for various users. Previous versions, such as 4.5, and 1.0, have paved the way for the current robust version.

CurveFitter brings a host of features that include handling user-defined equations with up to nine parameters and eight variables, as well as supporting linear and nonlinear exponential, logarithmic, and power equations. For those aiming to work with high-order polynomials and rationals, the tool incorporates a 38-digit precision math emulator ensuring highly accurate data fitting. After you fit your data, CurveFitter not only plots the fitted equations but also orders them by Standard Error, providing a comprehensive review of the curve fit results graphically. More
