DIFFERENCE OF SUM

Name:
    DIFFERENCE OF SUM (LET)
Type:
    Let Subcommand
Purpose:
    Compute the difference between the sums for two response variables.
Syntax:
    LET <par> = DIFFERENCE OF SUM <y1> <y2>
                            <SUBSET/EXCEPT/FOR qualification>
    where <y1> is the first response variable;
                <y2> is the first response variable;
                <par> is a parameter where the computed difference of the sums is stored;
    and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
    LET A = DIFFERENCE OF SUM Y1 Y2
    LET A = DIFFERENCE OF SUM Y1 Y2 SUBSET X > 1
