Second generation interferometric gravitational wave detectors, such asAdvanced LIGO and Advanced Virgo, are expected to begin operation by 2015. Suchinstruments plan to reach sensitivities that will offer the unique possibilityto test General Relativity in the dynamical, strong field regime andinvestigate departures from its predictions, in particular using the signalfrom coalescing binary systems. We introduce a statistical framework based onBayesian model selection in which the Bayes factor between two competinghypotheses measures which theory is favored by the data. Probability densityfunctions of the model parameters are then used to quantify the inference onindividual parameters. We also develop a method to combine the informationcoming from multiple independent observations of gravitational waves, and showhow much stronger inference could be. As an introduction and illustration ofthis framework - and a practical numerical implementation through the MonteCarlo integration technique of nested sampling - we apply it to gravitationalwaves from the inspiral phase of coalescing binary systems as predicted byGeneral Relativity and a very simple alternative theory in which the gravitonhas a non-zero mass. This method can trivially (and should) be extended to morerealistic and physically motivated theories.
