It assigns each group a bucket number starting from one. The partial autocorrelation function is a measure of the correlation between observations of a time series that are separated by k time units (y t and y t-k), after adjusting for the presence of all the other terms of shorter lag (y t-1, y t-2, , y t-k-1). • The LAG function is not called when the DATA step is processing the first observation for a competi-tor.
