## Editor's review

This is a statistical analysis program. It performs linear and nonlinear regression analysis or curve fitting.

DataFitting is a statistical analysis program that lets you do curve fitting easily through linear and nonlinear regression. DataFitting basically determines the values of parameters for an equation for an equation that you are trying to fit the data. The parameters that can best describe the data. The tool is able to manage linear, polynomial, exponential, and general nonlinear functions. The software tries true non linear regression not a linearized approximation of a nonlinear curve. It is thus able to handle functions that are impossible to linearize. The tool has a large set of equations inside it so that researcher, be it students, teachers, engineers, and others able to try out a wide variety of equations and decide on the best possible fit. The array of equations cover a range of models from simple linear equations to high order polynomials. Any user-defined equations of up to nine parameters and eight variables can be accommodated. The maths is backed by a 38-digit precision math emulator for properly fitting high order polynomial and rational coefficients.

The interface shows you the data, the parameters from curve fitting, in a format that is convenient for the mathematically minded. You can ask the program to do a charting so that you get a visual clue to how good the fit really is. **CurveFitter** program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. **Curvefitter** takes full advantage of the Windows user interface to simplify every aspect of operation from data import to output of results. Import data from text file. If you are into a lot of data fitting, this is a tool you should keep in your set of tools.
