causaldag.utils.invariance_tests.gauss_invariance.gauss_invariance_suffstat(obs_samples, context_samples_list)

Helper function to compute the sufficient statistics for the gauss_invariance_test from data.

Parameters:

• obs_samples – (n x p) matrix, where n is the number of samples and p is the number of variables.
• context_samples_list – list of (n x p) matrices, one for each context besides observational

Returns:

dictionary of sufficient statistics

Return type:
