exp_family_test Module

class infpy.exp.test.exp_family_test.CheckConjugatePrior(conj_prior)

Bases: object

Checks various methods/properties of a conjugate prior.

check_all()

Run all checks on this conjugate prior.

check_conjugacy()

Test that the conjugate prior is set up correctly.

check_log_normalisation_factor_expectation(sample_size=1000)

Test that we get close to the same expectation of the mvn normalisation factor from sampling from a normal wishart that we do from calculation of our formula.

conj_prior = None

The conjugate prior being checked.

class infpy.exp.test.exp_family_test.CheckExpFamily(family)

Bases: object

Checks various methods/properties of an exponential family.

check_KL(size=1000)

Checks the KL divergence by sampling.

check_against_truth()

Checks the family pdf agrees with the independently calculated pdf.

check_all()

check_attributes()

Checks the class has the correct attributes.

check_dimensions()

Checks the family has the correct length for A(), T() and eta().

check_entropy_truth()

Checks the family entropy agrees with the independently calculated entropy.

check_exp_T(size=10000)

Checks the expectation of sufficient statistics.

check_thetas()

Checks the family converts between eta and theta ok.

check_vectorisation()

Checks the family handles multiple xs and etas at once.

check_xs()

Checks the family converts between x and T ok.

family = None

The exponential family being checked.
