11.8 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.
