A Relationship Between Harris Factors and Guttman's Sixth Lower Bound To Reliability

Nicewander, W. Alan

Psychometrika, 40, 2, 197-203, Jun 75

Shows that the Harris factors of R have psychometric properties similar to those discussed by Kaiser and Caffrey (1965) and Bentler (1968). Specifically it is shown that the Harris factors of R maximize a lower-bound to the reliability of a composite measure derived by Guttman (1945). (Author/RC)
