The need for convergent validity in the measurement of personality variables and past failures to demonstrate such properties are briefly reviewed. Two apppoaches to the problem using several types of data obtained from various subject populations and employing alternative factor analytic methods and factor score estimation procedulres are described. The… (More)
AbstRAct Organizations are beginning to apply data mining and knowledge discovery techniques to their corporate data sets, thereby enabling the identification of trends and the discovery of inductive knowledge. Many times, traditional transactional databases are not optimized for analytical processing and must be transformed. This article proposes the use… (More)
Two common methods of measuring personality variables are examined with respect to the ways in which they control respondent biases. A form of the mental-test theory model is developed which makes explicit differences in score components that result from different methodological constraints imposed by the two methods. From the model, it is possible to… (More)
The formula for coefficient alpha for a component is developed. Kaiser's special formula for coefficient alpha for a principal component and the Kaiser-Guttman Rule for the "number of components" are mentioned. A numerical example is added. It is conjectured that the sum of coefficients alpha is invariant under orthogonal rotation.
