EUCLIDEAN LENGTHName:
<SUBSET/EXCEPT/FOR qualification> where <y> is the response variable; <par> is a parameter where the computed Euclidean length is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
LET A = EUCLIDEAN LENGTH Y SUBSET Y > 0
This command performs the same function as the VECTOR LENGTH command. The distinction is that EUCLIDEAN LENGTH is implemented as a Statistics LET subcommand while VECTOR LENGTH is implemented as a Mathematics LET subcommand. The Statistics LET subcommands work with the 25+ commands documented in HELP STATISTICS while the Mathematics LET subcommands do not.
