Here's one way. Another way would be to
do -statsby- separately for each variable
and -merge- the results. Another way
would be to -stack- your responses into
one variable and then apply -statsby-.
There are, no doubt, yet other ways.
One possible other way might be to use -parmby- (part of tthe -parmest-
package) instead of -statsby-, and to use the -regress- command to generate
the means for each variable, and then to use -dsconcat- to concatenate the
output data sets for each variable. For instance, John might write a program
