Signature

def nllf ( self , params = None , data = None )

Summary

Negative log-likelihood function

Extended Summary

Evaluates the negative of the log-likelihood function of the provided data at the provided parameters.

Parameters

params : tuple, optional: The shape parameters, location, and (if applicable) scale of the distribution as a single tuple. Default is the maximum likelihood estimates (self.params).
data : array_like, optional: The data for which the log-likelihood function is to be evaluated. Default is the data to which the distribution was fit.

Returns

nllf : float: The negative of the log-likelihood function.
