Poisson model probability mass function
Parameters: X : array-like
X
is the linear predictor of the model. See notes.Returns: pdf : ndarray
The value of the Poisson probability mass function, PMF, for each point of X.
Notes
The PMF is defined as
where assumes the loglinear model. I.e.,
The parameter
X
is in the above formula.
