Poisson.loglikeobs(params)[source]¶ Loglikelihood for observations of Poisson model
- Parameters
- paramsarray_like
The parameters of the model.
- Returns
- loglikearray_like
The log likelihood for each observation of the model evaluated at params. See Notes
Notes
\[\ln L_{i}=\left[-\lambda_{i}+y_{i}x_{i}^{\prime}\beta-\ln y_{i}!\right]\]for observations \(i=1,...,n\)
