AbstractIn ridit analysis scale values are assigned to the categories of an ordinal response variable, the ridits. Ridit analysis is described as a technique to compare groups of observations and to measure the association between ordinal and nominal variables by mean ridits. By their definition mean ridits are closely related to distribution‐free methods. Mean ridits are also used as a tool to test the main and/or interaction effects of factors on an ordinal response variabl

摘要:

AbstractWhen count data show extra‐Poisson variation, standard log‐linear techniques to analyse the data may fail. In ihis paper a generalization of the log‐linear modelling technique is proposed for the negative binomial model, as an extension of the Poisson model. An illustration is given by the analysis of a twoway classification of soldering failure data; extensions to more general classifications are pos

摘要:

AbstractA class of χ2‐type goodness‐of‐fit tests for the hypotheses of equal cell probabilities is introduced and the quality of the tests under arbitrary model restrictions is compared, where a suitable efficiency concept is used. As a special case, several nonparametric tests on treatment effects in the randomized block design can be considered. Some well known cases, such as the Anderson‐, Friedman‐ and the Page‐test, turn out to possess a certain minimax efficiency property under reasonable model assumptions. Finally a direct comparison between the Anderson‐ and Friedman

摘要:

AbstractThis paper presents the results of an experimental determination by Monte Carlo techniques of the power functions of a generalized Friedman's rank test based on “standardized” ranks and a proposed test procedure based on aligned ranks for orthogonal designs. The simulation is carried out for five orthogonal designs and a number of Normal location alternatives and gives some information about the difference in power of the two test procedures for some orthogonal desi

摘要:

AbstractWe consider the M/M/1‐queue and derive an explicit expression for the joint distribution of the number of arrivals and the number of departures in [0, t), given the number of customers initially present. The derivation is almost purely combinatorial, it avoids the use of generating functions, and immediately yields a simple probabilistic interpretation of the resul
