Extended tests for non-zero between-study variance
The ANOVA F-test, James tests and generalized F-test are extended to test hypotheses on the between-study variance for values greater than zero. Using simulations, we compare the performance of extended test procedures with respect to the actual attained type I error rate.
Examples are provided to demonstrate the application of the procedures in ANOVA models and meta-analysis.
