✦ Synopsis


Nous considerons un Cchantillon X1 ? . . . . X,, connu par les indicatrices des evenements {X, E ((M -1 + r)h,(M + r)h]}, 1 5 i 5 n, 1 < r 2 N. Now estimons la densite f des observations par des moyennes d'histogrammes bases sur des intervalles d'extremites dam {kh : k E N}. Nous montrons que ces estimateurs possedent des propriCk% de convergence et de simplicite a m&me de justifier leur utilisation en analyse statistique. 0 Academic des Sciences/Elsevier, Paris An intrinsic approach to nonparametric density estimation We consider samples Xl, . . . . X,, partially observed through the indicators of the events {X, E ((M -1 + r)h, (A4 + r)h]}, 1 5 % 5 76.1 < r 5 N. We estimate the underlying density f by averaging a class of histograms based upon intervals with endpoints in {kh : k E N}. We show that the resulting estimators are easy to use and have limiting properties which are bound to justify their use in statistical analysis. 0 Academic des Sciences/Elsevier. Paris
