We first describe the likelihood of the commonly used variance components model, for example as in Amos. 5 Since the total likelihood is a product of likelihood over all the families under study, we ...

This paper deals with confidence interval estimation and hypothesis testing for components of variance, in analysis-of-variance situations embraced by the Model II of Eisenhart [1], including also the ...

The design problem for the estimation of variance components by the method of unweighted squares of means, under a multifactor random effects model, is considered. First it is shown that with the ...
