The coefficient of variation (CV) of a population is defined as the ratio of the population standard deviation to the population mean. It is regarded as a measure of stability or uncertainty, and can indicate the relative dispersion of data in the population to the population mean. CV is a...

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...

KURZFASSUNG Auch wenn die "New Economy" schon seit längerer Zeit existiert, begann sie seit Mitte der Neunziger Jahre eine wichtige Rolle, nicht nur in der US-Wirtschaft, sondern in der gesamten Weltwirtschaft zu spielen. Es ist das Ziel dieser Arbeit zu erklären, wie die "New Economy" heute...

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...

In longitudinal studies, nonlinear mixed-effects models have been widely applied to describe the intra- and the inter-subject variations in data. The inter-subject variation usually receives great attention and it may be partially explained by time-dependent covariates. However, some covariates...

We consider strong limit theorems for Markov chains in bi-infinite random environments. We first give a new proof of a strong limit theorem of Liu and Yang (1995) on the average of functions of non-homogeneous Markov chains by constructing a nonnegative martingale. As corollaries, for a Markov...

Downs (1962) and Thomson (1977) suggested that highway capacity expansion may produce counterproductive effects on the two-mode (auto and transit) transport system (Downs–Thomson Paradox). This paper investigates the occurrence of this paradox when transit authority can have different economic...

Latent class models with crossed subject-specific and test(rater)-specific random effects have been proposed to estimate the diagnostic accuracy (sensitivity and specificity) of a group of binary tests or binary ratings. However, the computation of these models are hindered by their complicated...

A significant proportion of patients used the internet to obtain information about their disease. Age, employment status, educational level, and household average monthly income had an effect on internet usage for LC information. The use of the internet could cause mixed emotional outcomes among...
