 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.  The model formula can
 be entered in various ways after the key sequence ‘a F’ is pressed.
 
    If the letter ‘P’ is pressed after ‘a F’ but before the model
 description is entered, the data as well as the model formula will be
 plotted after the formula is determined.  This will be indicated by a
 “P” in the minibuffer after the help message.
