ABSTRACT
Comparative statements are in the heart of both differential (Anastasi, 1994) and person-oriented (Bergman, Magnusson, & ElKhouri, 2000) research. Not surprisingly, CFA methods of group comparison have experienced considerable attention and development. Methods for the comparison of two groups have been the farthest developed. In addition, there exist methods for the comparison of three and more groups. The present chapter reflects these developments. The most space will be devoted to the description of methods for the comparison of two groups.
