Abstract The methodological discussion in DeRoos‐Schaafsma(1981) Section 6 is continued by proposing asymptotic methods as a substitute for laborious confidence interval computati

摘要:

Abstract Previous authors have rejected the Poisson model for association football scores in favour of the Negative Binomial. This paper, however, investigates the Poisson model further. Parameters representing the teams' inherent attacking and defensive strengths are incorporated and the most appropriate model is found from a hierarchy of models. Observed and expected frequencies of scores are compared and goodness‐of‐fit tests show that although there are some small systematic differences, an independent Poisson model gives a reasonably accurate description of football scores. Improvements can be achieved by the use of a bivariate Poisson model with a correlation between scores o

摘要:

Abstract In this paper we propose distribution‐free treatments versus control tests for the one‐ and two‐way classifications. The null distribution properties are shown to be equivalent to those of well‐known statistics for which critical values have been extensively tabled. Asymptotic relative efficiencies with respect to corresponding normal theory competitors are derived and optimal designs for the allocation of experimental units to the treatments and control are

摘要:

Abstract We consider the problem of testing equality of the mean vectors of two multivariate normal populations when covariates are present and the covariance matrix is known. As an application of the Hunt‐Steintheorem it is shown that the χ2‐‐test of levelamaximizes, among all levelatests, the minimum power on each of the contours where the χ2‐‐test has constant power. A corollary is that the χ2‐‐test is mos

摘要:

Statitica Neerlandica had decided to encourage the reporting on theses in statistics, biometrics, econometrics and operations research, submitted at dutch universities.The man purpose of this section is to inform the reader briefly of the nature, the practical and theoretical importance, the methods used and the results presented in recent theses.It is understood that contributions to this section meet with the approval of the supervisor(s) of the thesis.Notes (in English and not exceeding 300 words) should be sent to the column editor.
