A Review of a Rotation to Obtain Maximum Similarity and Simple Structure Among Factor Patterns.
Under some circumstances, it is desirable to compare the factor patterns obtained from different factor analyses. To date, the best method of simultaneously achieving simple structure and maximum similarity is the technique devised by Bloxom (1968). This technique simultaneously rotates different factor patterns to maximum similarity and varimax simple structure and is applicable when the number of factors and variables are the same for each subpopulation. The technique is described and the computer algorithms are given. A numerical example compares the results of different factor analyses. If the limitations of the method are observed, Bloxom's rotation technique has the potential for wide application in studies involving comparison of factor patterns. A small loss in simple structure through the use of Bloxom's method often pays off in factors which can be much more meaningfully compared. (CK)
