摘要:

In regression models, the underlying theory frequently leads to specification of more than one functional form for the conditional mean of the response. The main problem in such cases is whether the differences between the models are sufficiently large relative to the variance of the disturbance term to warrant efforts to discriminate between the models or collect new data in order to discriminate. This paper, after refining the notion of differences between models, suggests several alternative statistics which might be useful in this problem and derives their asymptotic distributions.

摘要:

Two-stage Wilcoxon signed ranks tests and Wilcoxon-Mann-Whitney tests are presented for general one-sided alternatives. A probability recurrence relation is given for the two-stage signed ranks statistics under the null hypothesis. For each test the limiting bivariate distribution of the standardized statistics is normal. With certain restrictions on the sample sizes, the null limiting distributions are both the one considered by Owen [8], so large sample tests can be formed using existing tables. Monte Carlo results suggest that these tests can considerably reduce the expected number of observations without reducing power relative to the usual one-stage tests.

摘要:

The probability density function for the range of a sample from a population whose distribution can be represented by an Edgeworth series is developed. Moments of the range are obtained and the numerical values of the corrective functions arising due to non-normality tabulated. Results for moments of the range of various nonnormal distributions are compared.

摘要:

Assuming multivariate normality, a necessary and sufficient condition is derived for the validity of eachFratio in anL×J×Kfactorial design with repeated measurements on the last two factors. The condition is: C'Σ1C = C'Σ2C =…= C'ΣLC = σ2I, where C is the contrast matrix representing the comparison of interest, and Σi,i= 1, 2, …,L, is a(JK)×(JK)population dispersion matrix.
