The maximum Studentized range statistics was used by Copenhaver and Holland (1987, 19th Symp. on the Interface of Computer Science and Statistics, Philadelphia, PA; Copenhaver and Holland, 1988. J. Statist. Comput. Simulation 30, 1-15) to test the equality of treatment means in a two-way ANOVA....

In clinical trials with time to an event endpoint, the Wald test in a Cox regression model may be used to assess the difference between two treatments. In this paper, a Bartlett type correction to the Wald test is derived and applied to the analysis of data from a clinical trial on actuate...

The tobit censored response model plays an important role in analyzing the dependent variable with a constraint at a pre-specified point such as 0, and is widely used in econometrics research. For this regression model, there are few studies on variable selection in a group manner. In this...

 We consider the problem of comparing predictive intervals for a future observation via their expected lengths at a given confidence level. A higher order asymptotic theory is developed. This yields an explicit formula for expected length comparison and associated admissibility results....

The ordinary Bayesian information criterion is too liberal for model selection when the model space is large. In this paper, we re-examine the Bayesian paradigm for model selection and propose an extended family of Bayesian information criteria, which take into account both the number of unknown...
