It is just as simple
to create row or column percentages as it is to create cell percentages.
Just as PCTN and PCTSUM calculate percentages for table cells, the
ROWPCTN, ROWPCTSUM, COLPCTN, and COLPCTSUM statistics create row or
column percentages. In these examples, the goal is to calculate row
and column percentages of the total sum for each row and column. Because
we are looking at the sum, we use the ROWPCTSUM and COLPCTSUM statistics.
