On the Power of Jonckheere's k-Sample Test against Ordered Alternatives,
VICTORIA UNIV (BRITISH COLUMBIA)
Pagination or Media Count:
The power of Jonckheeres test for trend is considered for a particular class of nonparametric alternatives. A recursive formula is developed for computing the exact distribution of the test statistic. The mean and variance of the test statistic are derived. An approximation is developed based on the asymptotic distribution of the test statistic. Tables of exact and approximate power are given.
