# DIFFERENCE OF RANGE

Name:
DIFFERENCE OF RANGE (LET)
Type:
Let Subcommand
Purpose:
Compute the difference between the ranges for two response variables.
Description:
The range is the difference between the minimum and maximum value of a response variable.

For the differeence of ranges, the range is computed for each of two samples then their difference is taken.

Syntax:
LET <par> = DIFFERENCE OF RANGE <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 ranges is stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
LET A = DIFFERENCE OF RANGE Y1 Y2
LET A = DIFFERENCE OF RANGE Y1 Y2 SUBSET X > 1
