sample_intensities#

anri.fwd.sample_intensities(centroid, coord, inv_cov, norm_const)[source]#

Evaluate probability density of Mahalanobis distance.

See prepare_cov() for preparation of inv_cov and norm_const.

Parameters:

  • centroid (Array) – [N] Coordinate of peak centroid in N dimensions

  • coord (Array) – [N] Query coordinate in N dimensions

  • inv_cov (Array) – Inverse covariance matrix, from prepare_cov()

  • norm_const (float) – Normalisation constant, from prepare_cov()

Returns:

jax.Array – Probability density of an observation

Notes
