Nonparametric regression estimation onto a Poisson point process covariate
ESAIM: Probability and Statistics, Tome 19 (2015), pp. 251-267.

Let Y be a real random variable and X be a Poisson point process. We investigate rates of convergence of a nonparametric estimate r̂(x) of the regression function r(x) = 𝔼(Y|X = x), based on n independent copies of the pair (X,Y). The estimator r̂ is constructed using a Wiener–Itô decomposition of r(X). In this infinite-dimensional setting, we first obtain a finite sample bound on the expected squared difference 𝔼(r̂(X)-r(X)) 2 . Then, under a condition ensuring that the model is genuinely infinite-dimensional, we obtain the exact rate of convergence of ln𝔼(r̂(X)-r(X)) 2 .
