DataFitting is an easy-to-use and comprehensive nonlinear regression analysis program for Windows. It determines the values of parameters for an equation that cause the equation to best fit a set of data values that you provide. DataFitting uses a true nonlinear regression technique that minimizes the squared residuals for the actual equation. Using the program you can perform multivariate, linear quadratic, polynomial, exponential, periodic and complex nonlinear regression.
Quickly Find the Best Equations that Describe Your Data:
DataFitting 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. DataFitting's built-in library includes a wide array of linear and nonlinear models from simple linear equations to high order polynomials. DataFitting has the following capabilities:
* A 38-digit precision math emulator for properly fitting high order polynomials and rationals.
* A robust fitting capability for nonlinear fitting that effectively copes with outliers and a wide dynamic Y data range.
Graphically Review Curve Fit Results:
Once your data have been fit, DataFitting automatically sorts and plots the fitted equations by the statistical criteria of Standard Error. You can preview your graph and output publication-quality graphs in several different configurations. A residual graph as well as parameter output is generated for the selected fitted equation. Data, statistical and numeric summaries are also available from within the report-panel.
DataFitting is developed to help the children suffering from cancer in the "Save-the-Children" charity project of Children's Hospital, Helsinki, Finland.
