I do not have access to my books and papers at the
moment. I have been asked to review a paper that uses Multidimensional Scalogram Analysis. I have an impression that it is a generalization of Guttman scaling yielding dimensions along which cases are ordered. What kind of similarity/distances does it use? Are there methods that are mathematically the same thing as "multiple scalogram analysis" but have different names? Do you have a cite which states this equivalence? How does Multidimensional Scalogram Analysis compare to multiple correspondence analysis, dual scaling, or categorical PCA? The study uses dichotomous (2-valued) variables. Some of the the variables are a set that represents levels of a polychotomy. One of the dichotomies could be a trichotomy (yes, no, unknown). Now the "unknown" is collapsed collapsed into "no". -- What other methods would arrange the cases along dimensions given this kind of data? -- Art Kendall Social Research Consultants ---------------------------------------------- CLASS-L list.
