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 \(\tau\) ?'' The relationship is established between \(\tau\) 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.
