摘要:

AbstractThis paper shows that categorical data can be analysed by analysis of variance methods; applying least squares, linear additive models,F‐teste for significance and so forth. It enriches an alternative analysis which leads to chi‐square tests, c.f. author (1982), LIGHT and MARGOLIN (19

摘要:

AbstractThe performance of the standard confidence limits for a proportion is studied over the entire range of proportions, and for various prescribed values of the nominal confidence coefficient. In the light of the conservative nature of these limits, modifications are suggested resulting in limits with average confidence coefficients close to the 95% nominal value. A comparison is made with a solution obtained from the application of Bayes's theorem to the problem.

摘要:

AbstractRecurrence risks are compared to conditional recurrence risks under certain association models corresponding to the underlying semi‐symmetric intraclass contingency table. Ratios of mean squared errors are used to make the comparisons. A study of the comparisons corroborates the theory of KHAMIS and HINKELMANN (1984), and gives new insight into the disease‐genotype association prob

摘要:

AbstractThe model used in this paper isY=Xβ, where withunknownx0.Estimators ofx0are derived by putting βmx0=βm+1regarding βm+1as a new unknown parameter. Formally we use the modelY= X1β++ e where β′+= (β0, …βm+1andThen βm+1/ βmis a point estimator ofx0.Assuming normality foreand taking the random variable z=βmx0−βm+1we geta t‐distributed variable and finally a confidence estimator ofx0.The formulas are applied in dose response relations in antibiotic assays refering to a standard. Now we can take into account not only the dependence on the dose/concentration but also on the position on the test agar plate where the test solution is filled in. As a consequence the confidence interval of the unknown dose/concentrationx0becomes shorter and by it the stat

摘要:

AbstractFor multiple testing of multinomial models in the case of one or two samples we propose using test procedures based on the principle described by MARCUS, PERITZ and GABRIEL (1976). These methods are based in each step of the sequentially rejective strategy on tests which exhaust the full α level (i.e. which are not conservative). The tests can be performed in a finite or asymptotic version

摘要:

AbstractThe decomposition for the complete point symmetry model in a rectangular contingency table is shown. Also the respective decompositions for the local point symmetry model and the reverse local point symmetry model in a square contingency table are given. Moreover test procedures for the decomposed models and an example are given.
