Abstract

It is shown that the non-null distribution of a simple transform of the 2-variable intraclass correlation is central F. Hence, in principle, standard F-tables could be used to test hypotheses about intraclass correlations. In a simulation, Fisher's normal approximation was compared with the exact test for three different intraclass correlation estimates. Overall, the results were very close, confirming that Fisher's 2-transform is an excellent approximation even when the sample size is small.
