Sample Variances for Several MINQ-Estimators in the One-way Classification

A generalization of Ahrens' (1965) formulas for sample variances is done, considering the case of MINQ-Estimators which may be biased. The formulas are generally valid, but are restricted for the sake of simplicity to those of the one-way classification. Some MINQ-Estimators are considered and their sample variances calculated.
