FREQFIT -- Computer Program Which Performs Numerical Regression and Statistical Chi-Squared Goodness of Fit Analysis

摘要

The computer program FREQFIT is designed to perform regression and statistical chi-squared goodness of fit analysis on one-dimensional or two-dimensional data. The program features an interactive user dialogue, numerous help messages, an option for screen or line printer output, and the flexibility to use practically any commercially available graphics package (such as LOTUS 1-2-3, GNUPLOT, or Golden Software\u27s GRAPHER) to create plots of the program`s results.FREQFIT is written in Microsoft QuickBASIC, for IBM-PC compatible computers. A listing of the QuickBASIC source code for the FREQFIT program, a user manual, and sample input data, output, and plots are included.
