Confidence level of the fit

If the \CL qualifier is used, a new scalar, named FIT$CL , will be made with value equal to the confidence level:

where n is the degrees of freedom, usually equal to the number of data points minus the number of parameters, (N-M). The confidence level is the probability that a random repeat of the given experiment would observe a worse &chi2, assuming the correctness of the model.
