 Abstract: Thanks to the recent discoveries of gravitational wave signals from binary black hole mergers by Advanced LIGO and Advanced Virgo, the genuinely strong-field dynamics of spacetime can now be probed, allowing for stringent tests of general relativity (GR). One set of tests consists of allowing for parameterized deformations away from GR in the template waveform models, and then constraining the size of the deviations, as was done for the detected signals in previous work. In this paper we construct reduced-order quadratures so as to speed up likelihood calculations for parameter estimation on future events. Next we explicitly demonstrate the robustness of the parameterized tests by showing that they will correctly indicate consistency with GR if the theory is valid. We also check to what extent deviations from GR can be constrained as information from an increasing number of detections is combined. Finally, we evaluate the sensitivity of the method to possible violations of GR.
