Abstract
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.Keywords
