The goal of this module is to implement the probability of getting a given set
of extrinsics parameters for each detector (snr, horizon distance, end time and
phase) assuming that the event is a gravitational wave signal, *s*, coming from
an isotropic distribution uniform in location, orientation and the volume of
space. The implementation of this in the calling code can be found in
of extrinsic parameters for a set of detectors parameterized by n-tuples of
trigger parameters: (snr, horizon distance, end time and phase) assuming that
the event is a gravitational wave signal, *s*, coming from an isotropic
distribution in location, orientation and the volume of space. The
implementation of this in the calling code can be found in
:py:mod:`stats.inspiral_lr`.
The probabilities are factored in the following way:

in fact it appears that the reimplementation is a bit more sensitive.
