Abstract: | Measures of test parsimony and factor parsimony are defined. Minimizing their weighted sum produces a general rotation criterion
for either oblique or orthogonal rotation. The quartimax, varimax and equamax criteria are special cases of the expression.
Two new criteria are developed. One of these, the parsimax criterion, apparently gives excellent results. It is argued that
one of the most important factors bearing on the choice of a rotation criterion for a particular problem is the amount of
information available on the number of factors that should be rotated.
