Abstract
When familial data are analysed, the model usually employed assumes independence of family
observations and constancy of interclass and intraclass correlations. A statistic for testing the validity
of the assumptions of family independence and constant interclass and intraclass correlations is
developed. The test statistic is for constant family size; it has an asymptotic chi-square distribution.
An example to illustrate the theory is given using Frets's data on head lengths. A recommendation is
made on how to apply the test to the general case of varying family sizes. Another recommendation
is made on models to be tried once the null hypothesis is rejected.
