I'm using the (new) AggregateCells operator for calculating a moving average in SAS VA 8.3 like below
AggregateCells(_Average_, My measure, default,CellIndex(current, -4), CellIndex(current, 0))
Problem is that the first 4 periods return values instead of missing values. So for example for period 1 the moving average is calculated is an average of just the value of period 1. For period 2 the moving average is calculated is an average of just the values of period 1 and period 2. etc. This is not correct behavior in my opinion: I would not expect to see values for the first 4 periods when using this operator.
