Weight normalization
A list of weight variables can be specified using the weights-to-normalize
and weights-not-normalized
entries.
A product these variables will be used as weight, with its name chosen according to the following rule:
if only one variable is specified, its name will be used as the name of the weight variable;
otherwise, weight-var-name
needs to be specified to give name to the product variable.
The product is done in the following way:
- The variables specified in
weights-to-normalize
are multiplied and the resulting combined weight is normalized to the total number of entries. - The variables in
weights-not-normalized
are then multiplied to the previously normalized weight variable, and the result is the final weight.
