Question

relative merits & demerits of scalogram analysis?

Answer 1

Answer:

An examination of results from these applications revealed at least three potential limitations: (1) presumed drug usage patterns may not generalize to many drug users, especially adult users; (2) presumed patterns may not be supported if several commonly used psychoactive substances are included; and (3) measures of unidimensionality may not be sufficient for confirming actual unidimensionality of highly skewed drug use patterns.
