摘要：Lancaster''s additive approach to absence of interaction in contingency tables has been used frequently in agriculture in recent years, sometimes incorrectly. In this paper, the frequency distributions of response for a number of treatment groups which are factorially structured are compared. An additive model is proposed which allows for examination of the role of the individual factors in explaining any differences among responses. Test statistics are developed and the theory is illustrated ...

摘要：The theory of DA-optimum design of experiments is used to provide designs of the biased coin type for sequential clinical trials in the presence or absence, of prognostic factors. The designs avoid many arbitrary features of earlier schemes.

摘要：With k representing independent exponential populations with unknown and possibly unequal location parameters, and with a common but unknown scale parameter, a complete random sample of common size n is drawn from each population. Based on those k samples, a new range statistic for comparing these exponential location parameters simultaneously, is proposed.

摘要：The expected gain in information provided by an experiment is used to investigate the loss of information when observations on lifetimes in reliability and survival studies are censored. It is assumed that the lifetime distribution is exponential. The loss of inormation through only obtaining data at given time points is also considered.

摘要：When interim accumulated results from a clinical trial clearly indicate that the null hypothesis should be accepted or rejected, ethical and cost considerations may dictate terminating the trial and making the appropriate decision. Pocock (1977) described a group sequential procedure for clinical trials that permits early termination only for rejecting the null hypothesis. This paper extends Pocock''s procedure to allow early termination with acceptance of the null hypothesis. Theoretical and ...

摘要：The von Mises distribution in p dimensions is suggested for the analysis of data which are proportions of a continuum such as time or volume. The 1-way analysis-of-variance technique developed by Watson (1956) is extended to a multiway layout and the methods are illustrated on data giving proportions of time spent in various activities [student''s activities].

摘要：Several situations involving [patient] survival data are examined, in which the nonparametric maximum likelihood estimator is not the Kaplan-Meier estimator. Cases covered are inclusion of initial observations in field studies, estimation of the length distribution from convex window sampling of line segment processes in 2 dimensions and estimation of a survival curve with monotone density. The first 2 case are nonstandard because survival and censoring are not independent and thus form simple...
