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...

This paper presents and analyzes a survey taken of core (required) finance courses in the curricula of the highest-reputation MBA programs in the school year 2004-2005. Five of the nineteen schools responding have increased hours spent in the finance core substantially, compared to results of...

We propose that, in the pursuit of ongoing goals, optimistic expectations of future goal pursuit have greater impact on immediate actions than do less optimistic considerations, such as retrospections on past goal pursuit or less optimistic expectations. Further, we propose that the direction of...

Titanium dioxide doped Fe3+ and La3+ nano-composite films were prepared using the sol–gel method. The photo-catalytic properties were evaluated by photo-degradation of methyl orange in solution. Scanning electron microscope, X-ray diffraction, and energy dispersive spectrometer were used to...

The thick ceramic coatings were prepared on 6061 aluminum alloys by microarc oxidation in a silicate electrolyte. The morphology and phase constituent of the coatings with different thickness were studied by scanning electron microscope, and X-ray diffraction. Scratch and thermal shock tests...

We study the nonparametric k-sample test problem with panel count data. The asymptotic normality of a smooth functional of the nonparametric maximum pseudo-likelihood estimator (Wellner & Zhang, 2000) is established under some mild conditions. We construct a class of easy-to-implement...

In this paper, we study panel count data with covariates. A semiparametric pseudolikelihood estimation method is proposed based on the assumption that, given a covariate vector Z, the underlying counting process is a nonhomogeneous Poisson process with the conditional mean function given by E{N...

In this paper, we study panel count data with informative observation times. We assume nonparametric and semiparametric proportional rate models for the underlying event process, where the form of the baseline rate function is left unspecified and a subject-specific frailty variable inflates or...

This paper investigates the long-run equilibrium relationships, temporal dynamic relationships and causal relationships between energy consumption structure, economic structure and energy intensity in China. Time series variables over the periods from 1980 to 2006 are employed in empirical...

Objective: Expose the weak loops in the Chinese medical insurance coverage and uncover hospitals' role of over-pricing hospitalized insured patients compared with those non-insured. <P>Methods: A multi-linear regression method was used to analyze hospitalization expense for insured and uninsured...</p>
