Nonlinear regression analysis CurveFitter descriptionProgram that performs statistical regression analysis to estimate the values of parameters for different kind of functionsNonlinear regression analysis - CurveFitter software performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called "curve fitting".

Quickly Find the Best Equations that Describe Your Data
Curvefitter gives engineers and researchers the power to find the ideal model for even the most complex data, by putting a large number of equations at their fingertips.

Curvefitter's built-in library includes a wide array of linear and nonlinear models from simple linear equations to high order polynomials.
