csep.utils.stats.poisson_joint_log_likelihood_ndarray(target_event_log_rates, target_observations, n_fore)

Efficient calculation of joint log-likelihood of grid-based forecast.

Note: log(w!) = 0

Parameters:

• target_event_log_rates – natural log of bin rates where target events occurred

• target_observations – counts of target events

• n_fore – expected number from the forecasts

Returns:

joint_log_likelihood
