Abstract :
We consider the problem of estimating the density f of independent identically distributed couples {(Xk, Yk)}k which are the marks of an homogenous Poisson process, from samples {(Xk´,Yk´)}k deduced from {(X k, Yk)}k by a non-linear relation coming from the so-called Type II Counter Problem. From a relation between the probability density functions of the sequences, we propose an estimator of the pdf of Y, since common plug-in estimates are suboptimal
