  author={Jerome P. Keating and Ram C. Tripathi},
The F-test, F max-test and Bartlett's test are compared on the basis of power for the purpose of testing the equality of variances in two normal populations. The power of each test is expressed as a linear combination of F-probabilities. Bartlett's test is noted to be unbiased, UMPU, consistent against all alterna¬tives and the test which yields minimum length confidence intervals on the ratio of the variancesλ=σ1 2 /σ2 2 The two samples Bartlett critical values, although not recognized as such… CONTINUE READING
