Family.loglike()

Family.loglike(endog, mu, scale=1.0) [source]

The loglikelihood function.

Parameters:

Parameters:	`endog` : array Usually the endogenous response variable. `mu` : array Usually but not always the fitted mean response variable.
Returns:	llf : float The value of the loglikelihood evaluated at (endog,mu). Notes : ?? : This is defined for each family. endog and mu are not restricted to : `endog` and `mu` respectively. For instance, the deviance function : calls both loglike(endog,endog) and loglike(endog,mu) to get the : likelihood ratio. :

`endog` : array

Usually the endogenous response variable.

`mu` : array

Returns:
