<p>As <code>nonlin_curvefit</code> can be used instead of <code>nonlin_residmin</code>
for curve fitting (
see
<a href="nonlin_005fcurvefit.html#nonlin_005fcurvefit">nonlin_curvefit</a>,
see
<a href="nonlin_005fresidmin.html#nonlin_005fresidmin">nonlin_residmin</a>),
<code>curvefit_stat</code> can be used instead of <code>residmin_stat</code>
(
see
<a href="residmin_005fstat.html#residmin_005fstat">residmin_stat</a>) for statistics on the results of curve fitting.

<dd>
<p>Frontend for computation of statistics for fitting of values,
computed by a model function, to observed values.
</p>
<p>Please refer to the description of <code>residmin_stat</code>. The only
differences to <code>residmin_stat</code> are the additional arguments
<var>x</var> (independent values) and <var>y</var> (observations), that the
model function <var>f</var>, if provided, has a second obligatory argument
which will be set to <var>x</var> and is supposed to return guesses for
the observations (with the same dimensions), and that the possibly
user-supplied function for the jacobian of the model function has
also a second obligatory argument which will be set to <var>x</var>.
