TEST: add unit test of likelihood reweighting (!1252) · Merge requests · lscsoft / bilby · GitLab

We will be having an extended maintenance of https://git.ligo.org, https://containers.ligo.org, and https://docs.ligo.org on 7 May 2024 starting at approximately 9am PDT and lasting for three to four hours. This is to start the process of syncing the data from the current instance to the re-engineered instance we have been working with GitLab on over the past few months. Starting at approximately 9am GitLab will be put into maintenance mode, meaning that all services will be in read-only mode. Throughout the maintenance there may be several periods of downtime. Please address any comments, concerns or questions to the helpdesk.

Colm Talbot requested to merge reweight-unit-testing into master Apr 21, 2023

I realized during a review call with @simon-stevenson that we don't have any unit tests of the likelihood reweighting. I added two test cases:

no likelihood change means perfect reweighting
a known difference in likelihoods gives the expected weights and changes the evidence by an expected way.
