rxmc.likelihood_model.log_likelihood(mahalanobis_sqr: float, log_det: float, n: int)[source]#

Multivariate-normal log likelihood from pre-computed statistics.

Parameters:

  • mahalanobis_sqr (float) – Squared Mahalanobis distance $(y - y_m)^T Sigma^{-1} (y - y_m)$.

  • log_det (float) – $log det Sigma$.

  • n (int) – Number of data points.

Returns:

float – Log likelihood value.
