Curve Fitting
=============

The `a F' command fits a set of data to a "model formula", such as `y
= m x + b' where `m' and `b' are parameters to be determined.  For a
typical set of measured data there will be no single `m' and `b' that
exactly fit the data; in this case, Calc chooses values of the
parameters that provide the closest possible fit.
