<P>
If the <TT>\FREE</TT> qualifier is used, then the number of degrees of freedom
for the fit is output into an automatically created scalar named
<font color="orange"><code>FIT$FREE</code></font>.</p>
<p>
The number of degrees of freedom is either the number of data values minus
the number of parameters, or, if the <TT>\-ZEROS</TT> qualifier is also used, the
number of non-zero weights minus the number of parameters.</P>
