We consider an estimate of the mode of a multivariate probability density with support in d using a kernel estimate drawn from a sample . The estimate is defined as any in {} such that f n ( x ) = max i = 1 , , n f n ( X i ) . It is shown that behaves asymptotically as any maximizer θ ^ n of . More precisely, we prove that for any sequence ( r n ) n 1 of positive real numbers such that r n and r n d log n / n 0 , one has r n θ n - θ ^ n 0 in probability. The asymptotic normality of follows without further work.
