Coalescing compact binaries emitting gravitational wave (GW) signals, as recently detected by
the Advanced LIGO-Virgo network, constitute a population over the multi-dimensional space
of component masses and spins, redshift, and other parameters. Characterizing this population
is a major goal of GWobservations and may be approached via parametric models.We demonstrate
hierarchical inference for such models with a method that accounts for uncertainties in
each binary merger’s individual parameters, for mass-dependent selection effects, and also
for the presence of a second population of candidate events caused by detector noise. Thus,
the method is robust to potential biases from a contaminated sample and allows us to extract
information from events that have a relatively small probability of astrophysical origin.
