The argument is not modified on return.
This vector should have the same size as y.
This vector should have the same size as x.
There is no need to initialise this argument - the initial value for the fitting procedure is set to the sum of the histogram or Y array.
This argument must be modifiable, i.e. it can not be a constant nor an expression.
There is no need to initialise this argument - the initial value for the fitting procedure is set to the mean of the histogram or arrays.
This argument must be modifiable, i.e. it can not be a constant nor an expression.
There is no need to initialise this argument - the initial value for the fitting procedure is set to the RMS of the histogram or arrays.
This argument must be modifiable, i.e. it can not be a constant nor an expression.
sqrt(chi**2/(#points - #parameters))
This correction factor is equal to 1 if the errors to the data points have been assigned correctly.
Errors are only returned upon request. The corresponding arguments must be modifiable, that is, they can neither be constants nor expressions.
