ALAM and ALAS: Questioning Error Assignments in Unidimensional Guttman Scaling
Wimberley, Ronald C.
Educational and Psychological Measurement, 36, 2, 361-7, Sum 76
When researchers use the Guttman scalogram rather than multidimensional techniques, scalogram error assignment techniques should be questioned. An alternative to the customary minimizing error rule is suggested through ALAM and ALAS criteria which use ordinal information in scalable item marginals. (Author)
