PICARD Paris ~UMMARY Conlribulzon Sludy of Aulomobile claims amounts After having look at the results obtained by adjustment of automobile claims amounts dmtr~bution, we research how the number and the time- configuration of past clailns condition the claHns law of probability. have statistics about group of 47 ooo cars whmh was followed for three years 7970, ~971 and r972. use naathematical technics and among multi-dimenslonal analysis, we use factorial analysis of corrcspondancc (A F.C. permits us to show the link Much exists between the clam1 amount of the tlnrd 3-ear and the nltmber of clalnas durmg the two years before. quantveatlve analysis of the corporal claims shows tl)at, of the frequency of corporal claHns during the third year growths up in functton of the number of paat clatms, the expected corporal claims amount of the third year decreases as the square of the material elamis number during the two first years [.
