The !TOTMAC macro in Figure D.8 can produce a variety of group summary statistics
such as sum, mean, and standard deviation for any SPSS-format data file. In the macro
call you specify values of keyword arguments indicating the data file (FILE), the break
(grouping) variable (BREAKVR), the summary function (FUNC), and the variable to be
used as input to the summary function (INVAR). For example, to obtain mean absences
for each classroom, we specify SCHOOL.SAV as the data file, CLASS as the break variable,
MEAN as the summary function, and ABSENT as the variable whose values are to
be averaged.
