ABSTRACT
This chapter concerns testing and estimation of differences in location among multiple groups. The simplest example of blocking is that of paired observations; paired observations are considered after Gaussian techniques. Techniques appropriate when observations are well-approximated by a Gaussian distribution are well-established. A statistic dependent on the unknown parameter was constructed, and estimates and confidence intervals were constructed by finding values of the parameter equating the statistic to appropriate quantiles. Benard and Elteren present a numerical method that uses the rule of Cramer to produce the matrix product involved in T. Prentice performs these calculations in somewhat more generality, and the general unbalanced two-way test is generally called the Prentice test.
