freeze_parameter

def freeze_parameter (   self,   param_index   ) Set the indexed parameter to be frozen in the fit. Freezing the parameter cuases its row and column to be set to the identity in the design matrix. It can be used to prevent very unstable parameters in a fit from drifting away from their starting values until more stable ones have been allowed to converge.
