In this paper, we present a comprehensive study of the monotonicity and log-concavity of the generalized Marcum and Nuttall Q-functions.More precisely, a simple probabilistic method is firstly given to prove the monotonicity of these two functions.Then, the log-concavity of the generalized Marcum Q-function and its deformations is established with respect to each of the three parameters.Since the Nuttall Q-function has similar probabilistic interpretations as the generalized Marcum Q-function, w...
