Loglikelihood of Poisson model

Parameters:

Parameters:	params : array-like The parameters of the model.
Returns:	The log likelihood of the model evaluated at `params`

params : array-like

The parameters of the model.

Returns:

The log likelihood of the model evaluated at params

$\ln L=\sum_{i=1}^{n}\left[-\lambda_{i}+y_{i}x_{i}^{\prime}\beta-\ln y_{i}!\right]$
