Abstract

When making between-group time use comparisons, it is often useful to have a single measure that summarizes the dissimilarity between the two groups. This paper examines the robustness of four alternative dissimilarity indexes. The main finding is that unweighted indexes, such as the Szalai T, are sensitive to the level at which activities are aggregated, while weighted indexes are robust to the level of aggregation.
