Window analysis

Tabular method for examining the changes in the efficiencies of a set of units over time. A set of time periods (1 ..t) is chosen and the efficiency of each unit (1..n) is computed separately for each period so that the efficiency of a given unit over each period is treated as a new unit resulting in a total number of tn units.

    Hi
    In Window analysis Are both constant return to scale and variable return to scale, applicable?
    Is the mean of all the efficiency scores for each DMU (in different periods) a suitable representative for the efficiency trend?
