Empirical results from long-horizon regression tests have been influential in the finance literature. Yet, it has come to be understood that traditional long-horizon tests may be unreliable in finite samples when regressors are persistent and when the horizon is long relative to sample size....

This article demonstrates how to construct a 1 - [alpha] level confidence set naturally associated a size [alpha] two-sided sequential test of a normal mean [mu]. If the null hypothesis H0: [mu] = 0 is rejected by the test, then the confidence set provides a one-sided confidence interval...

The problem of simultaneous inference and multiple comparison for comparing means of k( = 3) populations has been long studied in the statistics literature and is widely available in statistics literature. However to-date, the problem of multiple comparison of regression models has not found its...

In this paper, some nonparametric approaches of density function estimation are developed when censoring indicators are missing at random. A conditional mean score based estimator and a mean score estimator are suggested, respectively. The two estimators are proved to be asymptotically normal...

Today's business success to a great extent depends on logistics and supply chain performance. More and more companies, especially manufacturing firms, obtain their competitive advantages through creating successful logistics outsourcing alliances to optimise value and performance. This paper...

Semiparametric nonlinear mixed-effects (NLME) models are very flexible in modeling long-term HIV viral dynamics. In practice, statistical analyses are often complicated due to measurement errors and missing data in covariates and non-ignorable missing data in the responses. We consider...

This article maps out how different actors are involved in the promotion and mediation of the Olympics. It looks at the roles of, first, the nation-state, through an analysis of the promotional materials; second, the art world and global companies, through an analysis of the touring exhibition...
