Purpose

  List or store fit results.

Example

  ...
  FPEAKS 7
  FIT
  FRESULT / STORE(result)
  IPAR result / list

  will store the values of 21 fit parameters and fit parameter errors in
  global parameter result. When listed, the layout is as follows:

  RESULT(1..21,1..3) double          /* fres
  <value of fit parameter # 1> <positive error> <negative error>
  ...
  <value of fit parameter #21> <positive error> <negative error>

List of numbers of the component (partial) fit functions to be selected
(see also command FLAST).
If omitted, the complete fit function is taken.

Fit parameters are requested. This is the default.

The matrix of correlation coefficients is requested.

List of x-values the fit function is evaluated for.
xval may also be specified as from TO to BY step
(with step=1 by default).

Name of a flaoting point global parameter array to receive the specified fit results
(STATISTICS, FUNCTION(),CORR or PARAMETERS).
A 1-dimensional array is sufficient for statistics, function values or fit parameters.
If the destination array is 2- or more dimensional and has sufficient
bounds, the respective results are stored columnwise, containing the
following items per row:

   for PARAMETERS: fit parameter, positive and negative error,
   for FUNCTION(): x-value, function value, negative and positive function error,
   for CORR      : correlation coefficients per fit parameters,
   for STATISTICS: chi-square, number of degrees of freedom and the probability.

For 0 < co < 1 the evaluated function and fit parameter errors correspond to confidence limit co.
Usually co = 0.683 corresponds to the propagated error bars of the fitted input data.

Write results into the current picture

For peak functions the variance is listed instead of the FWHM.

Requests statistical information:
the values of chi-square, the number of degrees of freedom and the probability.
