HP 48G Linear Regression Best Fit Line

[Rodger Rosenbaum]

Note that the first thing in the little program I gave in the previous post is the LR function.

If the data are entered into the statistics registers in the usual way, the advantage of doing it this way is that you can have access to the two ways of fitting. If you execute LR, you get the ordinary least squares result; if you run the ORTH program, you get orthogonal least squares; comparison of the two is easy.
