摘要:

AbstractThe degree of agreement between two raters is re‐examined. An alternative statistic which uses the chi‐square distribution is proposed. We conclude that this statistic is better than the usualk‐statistic when the classification variable is at least or

摘要:

AbstractEdge‐corrected kernel‐based estimators are proposed for the pair‐correlation functiong(t). These estimators are compared by simulation methods with the existing edge‐corrected estimator suggested by FIKSEL (1988, Statistics, 19, 67–75). The results of the simulation study suggests that all the edge‐corrected estimators are almost unbiased. Furthermore, the estimators proposed in this paper have a smaller mean squared error than the existing alternative. Finally, the catoptrophorus semipalmatus nesting pattern

摘要:

AbstractIn the present paper, simultaneous prediction intervals are constructed for some mortality measures involving real data in a recent retrospective epidemiologic study of a cohort of man‐made mineral fiber workers. The object is to compare a test population with a standard population in which the workers are exposed to several levels (sayK) of a suspected carcinogen and the number of deaths in theKexposure groups are recorded. The SMR is chosen as a mortality measure for this comparison. If the total number of deaths d. in the entire study is known, the number of deaths in the various strata become dependent random variables. Using univariate statistical procedures to test the significance of the individual SMR's is inappropriate and may give misleading conclusions. The present paper shows how to test the simultaneous statistical significance of the SMR's of theKexposure groups, i.e., to test the simultaneous null hypothesisHo: E(SMR1) =E(SMR2) =…E(SMRk) = 100. If the null hypothesisHois rejected, it is shown how to identify the SMR (or the SMR's) which contributed to the rejection ofHo. The power function of such a test is also constructed for some simple and useful alternative hypothe
