Description

class containg the result of the fit and all the related information (fitted parameter values, error, covariance matrix and minimizer result information) Contains a pointer also to the fitted (model) function, modified with the fit parameter values. When the fit is valid, it is constructed from a Minimizer and a model function pointer

True if fit successful, otherwise false. A fit is considered successful if the minimizer succeded in finding the minimum. It could happen that subsequent operations like error analysis (e.g. Minos) failed. In that case the status can be still true if the original minimization algorithm succeeded in finding the minimum. One can query in that case the minimizer return status using Status(). It is responability to the Minimizer class to tag a found minimum as valid or not and to produce also a status code.
