CANBERRA DISTANCE

CANBERRA DISTANCE (LET)

Let Subcommand

Compute the Canberra distance between two variables.

The Canberra distance between two variabes X and Y is defined as
\( D = \sum_{i=1}^{n} {\frac{|X_{i} - Y_{i}|} {|X_{i}| + |Y_{i}|}} \)

The Canberra distance is a weighted version of the Manhattan distance.

LET <par> = CANBERRA DISTANCE <y1> <y2>
                        <SUBSET/EXCEPT/FOR qualification>
where <y1> is the first response variable;
            <y2> is the second response variable;
            <par> is a parameter where the computed Canberra distance is stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

LET A = CANBERRA DISTANCE Y1 Y2
LET A = CANBERRA DISTANCE Y1 Y2 SUBSET Y1 > 0 SUBSET Y2 > 0
