Fit Programs

The plots and fits can be performed via several Web interfaces. The interfaces submit your data to Linux programs running on the Web server. If you have some Linux and programming experience, you can also download the programs and macros and work with them locally on your computer.

Part A
    χ² Fit using a Lorentz function;
    Plot Y vs. X.

Part B
    Linear regression for data with two quantities measured with errors;
    Linear χ² fit (with one error);
    Linear fit without errors.

And here is a χ²/n.d.f. plot for some P-values.
