Abstract

In survey research it is not uncommon to ask questions of the following type: “How many times did you undertake action a in reference period T of length τ?.” The relationship is established between τ and the correlation of the number of reported actions with some background variable. To this end it is assumed that the process of actions satisfies a renewal model with individual heterogeneity. Also a model has to be formulated for possible recall effects. Applications are given in the field of medical consumption.
