WEIGHTED SUM OF ABSOLUTE VALUESName:
where X is the response variable and W is the weights variable. The response variable and weights variable must have the same number of observations.
For this command, the weights are not normalized. However, at least one of the weights must be positive and none of the weights can be negative. Otherwise, an error message is reported.
where <x> is the response variable;
<w> is the weights variable;
<par> is a parameter where the weighted sum of absolute values is saved;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
LET A = WEIGHTED SUM OF ABSOLUTE VALUES Y1 WEIGHT SUBSET Y1 > 0
LET Y = DATA 2 3 -5 7 11 13 -17 19 23 LET W = DATA 1 1 0 0 4 1 2 1 0 . LET A = WEIGHTED SUM OF ABSOLUTE VALUES Y WThe returned value is 115.
