TL;DR: The sequential tests of MIL-STD 781-B are based upon the accumulated test hours of a number of test units as discussed by the authors, but the number of units is not specified and may be varied to suit the testing agency.
Abstract: The sequential tests of MIL-STD 781-B are based upon the accumulated test hours of a number of test units. The number of test units, however, is not specified and may be varied to suit the testing agency. The problem here is to find the optimum number o..

TL;DR: In this paper, a Monte Carlo sampling technique was used to determine approximate critical values for the Kruskal and Wallis H-test when three, four or five populations are involved.
Abstract: A Monte Carlo sampling technique was used to determine approximate critical values for the Kruskal and Wallis H-test when three, four or five populations are involved. The critical values obtained can be used instead of the very conservative chi-square ..
TL;DR: The analysis of variance is a technique for comparing treatment means or for estimating components of variation as mentioned in this paper, which can be classified into two types: fixed effects analysis of the variance and random effects analysis.
Abstract: The analysis of variance is a technique for comparing treatment means or for estimating components of variation. The former is called fixed effects analysis of variance and the latter is called random effects analysis of variance. Many nonstatisticians ..
