## Abstract

Rates of convergence of Bayesian nonparametric procedures are expressed as the maximum between two rates: one is determined via suitable measures of concentration of the prior around the "true" density f(0), and the other is related to the way the mass is spread outside a neighborhood of f(0). Here we provide a lower bound for the former in terms of the usual notion of prior concentration and in terms of an alternative definition of prior concentration. Moreover, we determine the latter for two important classes of priors: the infinite-dimensional exponential family, and the Polya trees.
