In Facets, give each Likert item its own Models= statement with the
weighting you want. For instance,
Facets = 3
?,?,1,R6,2.3 ; give item 1 (facet 3) on a rating scale with
highest category 6, a weighting of 2.3
?,?,2,R6,1 ; give item 2 a weighting of 1
For more information and other approaches, see "Data weighting and
replication" in Facets Help.
