In this paper 12 blind transformation procedures are applied to 18 data sets. The results of the analyses indicate that the orthotran transformation solution is not restricted to particular types of data as are so many other transformation solutions. The evidence presented in this paper strongly suggests that the orthotran solution must be considered as the best blind analytic oblique transformation procedure presently available for general use. That is, the orthotran solution can be used by the average educational researcher without the bothersome consideration of the general nature of the factor matrix to be transformed. (Author)
