The TABLE statement creates a row for each value of Division and a column for each
value of Type. Because Type is crossed with Expenditures, the value in each cell is the
sum of the values of Expenditures for all observations that contribute to the cell.
Within each row, the TABLE statement nests four statistics: SUM and three different
calculations of PCTSUM (see Figure 48.5 on page 1233). Each occurrence of PCTSUM
uses a different denominator definition.

u sums the values of Expenditures for all occurrences of Type within the
same value of Division. Thus, for Division=1, the denominator is $7,477 + $5,129.
v sums the frequency counts for all occurrences of Division within the
same value of Type. Thus, for Type=1, the denominator is $7,477 + $19,379 +
$5,476 + $13,959.
w The third use of PCTN has no denominator definition. Omitting a denominator
definition is the same as including all class variables in the denominator
