Location estimates for single samples

1989
In Chapters 2 to 7 we consider data that are either measurements or ranks specifying order of magnitude or preference. The latter are called ordinal data. Chapters 2 and 3 are devoted to single samples. Most practical problems involve comparison of, or studying relations between, several samples, but many basic nonparametric notions are applicable also

Choosing a Two-Sample Location Test

The Journal of Experimental Education, 1994
Abstract Type I error rate and power for the t test, Wilcoxon-Mann-Whitney (U) test, van der Waerden Normal Scores (NS) test, and Welch-Aspin-Satterthwaite (W) test were compared for two independent random samples drawn from nonnormal distributions. Data with varying degrees of skewness (S) and kurtosis (K) were generated using Fleishman's (1978) power

Locating Sampling Points for Cubic Splines

1988
Locating sampling points for cubic splines is investigated in this paper. The direct application of the proposal is for designing motion of objects for computer animation. The method consists of two parts: (i) obtaining the relative position of the sampling points, and (ii) mapping the sampling points on the cubic spline interpolant based on the ...

Two-Sample Rank Procedures for Location

1981
The previous chapters dealt with inference procedures applicable in one-sample (or paired-sample) problems. We now consider the situation where there are two mutually independent random samples, one from each of two populations. We discuss tests which apply to the null hypothesis that the two populations are identical and the confidence procedures ...
