On Measuring Convergence in the Use of Time

In the study of the effects of retirement on the allocation of time, this paper discusses methods that evaluate convergence in patterns of time use. Scalar measures of multivariate scatter are revealed to be a more general method than previous devices utilized in the time-use literature. However, since time devoted to some activities could be correlated with time devoted to others, the degree of scatter observed in the data tend to be affected by the level of activity aggregation selected by the researcher.
