## @deftypefn {Function File} {@var{info} =} curvefit_stat (@var{f}, @var{p}, @var{x}, @var{y}, @var{settings})
##
## Frontend for computation of statistics for fitting of values,
## computed by a model function, to observed values.
##
## Please refer to the description of @code{residmin_stat}. The only
## differences to @code{residmin_stat} are the additional arguments
## @var{x} (independent values) and @var{y} (observations), that the
## model function @var{f}, if provided, has a second obligatory argument
## which will be set to @var{x} 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}.
##
## @seealso {residmin_stat}
