Some aspects of estimators in analysis of variance Model II. [PDF]

open access: yes, 1971
It is well known that the standard estimator for variance components in analysis of variance, Model II, can be a negative with positive probability. In practice, when such an estimator is found to be negative it is taken to be zero.
