Least Squares Curve Fitting

A program is available on the Macintosh systems for least squares fitting of numerical data to a functional form. Invoke the following sequence of actions:

Enter your data in "spreadsheet format"

First you have to plot the data. You must indicate which column of data is to be plotted on the x or the y axis;

Once plotted, a least squares analysis can be carried out;

You have a variety of functional forms "built-in" to the the program. You can also define your own form, which can be "non-linear" if desired.

Click on "Fit", when the coefficients of the functional form are displayed, along with the standard deviations.
