EqFit(TM) for Windows, Equation Fitting Tools, Version 4, [ASP/ESC]    


PROGRAM DESCRIPTION

EqFit(TM) has a multiple Regression Workbench to build and test trial equations against your data. Transform data as needed. View the results using graphical plots and any of five statistical output reports. Graph data, residuals, calculated Y, probability, and more. Watch the graphs change as you revise your regression equation. Predict Y using the new equation.

Print graphs and print or save calculated results to a file. Use ASCII or dBase files to input data. Create or edit data in the EqFit grid. Regression benchmarks are included to satisfy quality concerns. Also included are Descriptive Statistics and Histograms to analyze a column of data and Simple Regression (X-Y) to try a fit with 12 different equation forms.

The data file, EFTest.dat, is used as an example in all of the help files. The results of fitting an equation to this data are shown in file EFTest.txt. You might want to use this data for your first trial run.

The trial version of EqFit in this package is limited to a 15 day trial period and 5 uses. The program will become unusable afterwards. You are encouraged to purchase the registered version before the expiration time occurs. To purchase EqFit see the section below:
