ABSTRACT

This study analyzes the minimum dimension of statistically sufficient aggregation when performance measures are joint-normally distributed. Statistically sufficient aggregates incur no loss of information during the aggregation process and provide robustness to performance evaluation systems. This study shows that there is no one-dimensional statistically sufficient aggregate in a multi-task setting.
