Abstract
Let (Xn,Yn)n≤1 be a Rd
R valued stationary process. Define the estimator of the conditional mode of Y1 given X1=x as the random variable θn(x) that maximizes a kernel estimator of the conditional density of Y1 given X1 = x. We establish asymptotic normality of θn(x) when the process (Xn,Yn)n≤1 is assumed to be strongly mixing. We derive from our results asymptotic normality of a predictor and propose a confidence bands for the conditional mode function. A simulation study shows how good the normality of the conditional mode function estimator is when dealing with samples of finite sizes.
