A Confidence Interval Approach for Variance Component Estimates in the Context of Generalizability Theory.

Smith, Philip L.

Educational and Psychological Measurement, v42 n2 p459-66 Sum 1982

Monte Carlo methods are used to explore the accuracy of a method for establishing confidence intervals for variance component estimates in generalizability studies. Previous research has shown that variance component estimation errors due to sampling are often larger than suspected. (Author/CM)
