Gaussian.loglike_obs(endog, mu, var_weights=1.0, scale=1.0)
[source]
The log-likelihood function for each observation in terms of the fitted mean response for the Gaussian distribution.
Parameters: |
|
---|---|
Returns: |
ll_i – The value of the loglikelihood evaluated at (endog, mu, var_weights, scale) as defined below. |
Return type: |
float |
If the link is the identity link function then the loglikelihood function is the same as the classical OLS model.
where
If the links is not the identity link then the loglikelihood function is defined as
