EUCLIDEAN DISTANCEName:
The Euclidean distance is the straight line distance between two points in Euclidean space.
<SUBSET/EXCEPT/FOR qualification> where <y1> is the first response variable; <y2> is the second response variable; <par> is a parameter where the computed Euclidean distance is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
LET A = EUCLIDEAN DISTANCE Y1 Y2 SUBSET Y1 > 0 SUBSET Y2 > 0
This command performs the same function as the VECTOR DISTANCE command. The distinction is that EUCLIDEAN DISTANCE is implemented as a Statistics LET subcommand while VECTOR DISTANCE is implemented as a Mathematics LET subcommand. The Statistics LET subcommands work with the commands documented in HELP STATISTICS while the Mathematics LET subcommands do not.
