Background Evaluation of liver fibrosis is important to assess prognosis and guide the treatment for chronic hepatitis B. Objective To analyze and compare transient, point, and two-dimensional (2D) shear wave elastography techniques in grading the liver fibrosis. Methods Based on the severity of liver inflammation and fibrosis (Scheuer criteria), 158 patients with chronic hepatitis B were assigned...
Special Treatment (ST) is a particular regulation for the exchange to prompt the risk to investors. Since ST count data are discrete, traditional Orthogonal Least Square method cannot get better goodness of fitting. However, Poisson regression is appropriate to be used to analyze discrete data. In addition, once it is over-dispersed, Negative Binomial (NB) regression model is more suitable. In this...
In financial times series analysis, unit root test is one of the most important research issues. This paper is aimed to propose a new simple and efficient stochastic simulation algorithm for computing Bayes factor to detect the unit root of stochastic volatility models. The proposed algorithm is based on a classical thermodynamic integration technique named path sampling. Simulation studies show that...
