Confidence intervals on the ratio of expected mean squares \((\theta _ 1+\theta _ 2+\theta _ 3)/\theta _ 4\)
This paper considers two methods for constructing confidence intervals on the ratio of expected mean squares \((\theta_ 1+\theta_ 2+\theta_ 3)/\theta_ 4\) in a random model. Numerical integration shows that a modified large sample approximation provides an interval with a confidence coefficient close to the stated level.
