You can use aggregate (or summary) functions to summarize
the data in your tables. These functions can act on
multiple columns in a row or on a single column across rows.
Avg average of values •
NMiss number of missing values
Count number of non-missing values
• Prt probability of a greater absolute value of Student’s t
. CSS corrected sum of squares.
Freq (same as Count)
Nmiss,STDERR,MEan,Min,MAx etc
