1424 REPORT
means of all three variables. The third line displays the number of valid cases for XVAR
in the report column for XVAR.
• Every time the value of AVAR changes within each value of BVAR, the three summary
lines requested for BVAR are displayed. These summary lines are based on cases with the
current values of BVAR and AVAR.
Example
SORT CASES BY DEPT.
REPORT FORMAT=AUTOMATIC
/VARIABLES=WAGE BONUS TENURE
/BREAK=DEPT (23)
/SUMMARY=SUM(WAGE BONUS) MEAN(TENURE) ’Sum Income: Mean Tenure’.
• SUMMARY defines a summary line consisting of the sums of WAGE and BONUS and the
mean of TENURE. The result of each aggregate function is displayed in the report column
of the variable for which the function is calculated.
• A title is assigned to the summary line. A width of 23 is defined for the break column to
accommodate the title for the summary line.
Composite Functions
Use composite functions to obtain statistics based on aggregated statistics, to place a summary
statistic in a column other than that of the report variable for which it was calculated, or to
manipulate variables not named on VARIABLES.
• Composite functions can be computed for the following aggregate functions: VALIDN,
SUM, MIN, MAX, MEAN, STDEV, VARIANCE, KURTOSIS, SKEWNESS, PGT, PLT, and PIN.
Constants can also be arguments to composite functions.
• When used within composite functions, aggregate functions can have only one variable
as an argument.
• A composite function and its arguments cannot be separated by other SUMMARY
specifications.
• The result of a composite function can be placed in any report column, including columns
of dummy or string variables, by specifying a target column. To specify a target column,
enclose the variable name of the column in parentheses after the composite function and its
arguments. By default, the results of a composite function are placed in the report column
of the first variable specified on the composite function that is also specified on VARIABLES.
• The format for the result of a composite function can be specified in parentheses after the
name of the column location, within the parentheses that enclose the column-location
specification.
DIVIDE(arg 1 arg 2 [factor]) Divide the first argument by the second and then multiply the result
by the factor if it is specified.
MULTIPLY(arg 1 ... arg n ) Multiply the arguments.
PCT(arg 1 arg 2 ) The percentage of the first argument over the second.
SUBTRACT(arg 1 arg 2 ) Subtract the second argument from the first.
