An Empirical Comparison of Several Interval Estimation Procedures for Coefficient Alpha
Pandey, Tej N.; Hubert, Lawrence
Psychometrika, 40, 2, 169-81, Jun 75
Use of Tukey's Jackknife in establishing a confidence interval around the population coefficient alpha is explored and the robustness of Feldt's procedure along with ten variants of the Jackknife when the data do not conform to the necessary normality requirements are evaluated. Only two of the variants compared to Feldt's approach. (RC)
