摘要:

In this article, the correctedFstatistic in the general linear model is shown to be algebraically equivalent to the corresponding statistic in the weighted least squares procedure, whenever the correctedFstatistic exists. Hence, weighted least squares analysis is, in effect, a self-correctedFtest procedure.

摘要:

Most business statistics courses and textbooks teach quality control concepts in isolation from fundamental statistical concepts. In this article we present a way of organizing materials for introducing quality control concepts early in the business statistics course. We also show how these concepts can be integrated into the main flow of such a course. In addition, we demonstrate how this organization enhances the discussion of classical statistical inference topics.

摘要:

This department publishes articles of interest to statistical practitioners. Innovative applications of known methodology may be suitable, but sizable case studies should be submitted to other journals. Brief descriptions and illustrations of new developments that are potentially useful in statistical practice are appropriate. Acceptable articles should appeal to a substantial number of practitioners.

摘要:

Naively displaying a large collection of curves by superimposing them one on another all on the same graph is largely uninformative and aesthetically unappealing. We propose that a simple principal component analysis be used to identify important modes of variation among the curves and that principal component scores be used to identify particular curves which clearly demonstrate the form and extent of that variation. As a result, we obtain a small number of figures on which are plotted a very few “representative” curves from the original collection; these successfully convey the major information present in sets of “similar” curves in a clear and attractive manner. Useful adjunct displays, including the plotting of principal component scores against covariates, are also described. Two examples—one concerning a data-based bandwidth selection procedure for kernel density estimation, the other involving ozone level curve data—illustrate the ideas.

摘要:

This department includes the two sectionsNew Developments in Statistical ComputingandStatistical Computing Software Reviews; suitable contents for each of these sections are described under the respective section heading. Articles submitted for the department, outside the two sections, should not be highly technical and should be relevant to the teaching or practice of statistical computing.
