This paper analyzes some typical points of view on how to build the logistics standardization form in China and brings out the new logistics standardization form that is suitable for the practice. In the end, the paper proposes some suggestions on Chinese logistics standardization.展开更多

Further, it analyzes the status quo, market demand and problems existing in Yunnan's international logistics and puts forward proposals as how to develop international logistics aiming at Southeast Asia in Yunnan province.展开更多

Many covariates are inherently continuous, and have a variety of distributions, including those that are heavily skewed to the left or right. Existing theoretical formulas, criteria, and simulation programs cannot accurately estimate the sample size and power of non-standard distributions. Therefore, we have developed a simulation program that uses Monte Carlo methods to estimate the exact power of a binary logistic regression model. This power calculation can be used for distributions of any shape and covariates of any type (continuous, ordinal, and nominal), and can account for nonlinear relationships between covariates and outcomes. For illustrative purposes, this simulation program is applied to real data obtained from a study on the influence of smoking on 90-day outcomes after acute atherothrombotic stroke. Our program is applicable to all effect sizes and makes it possible to apply various statistical methods, logistic regression and related simulations such as Bayesian inference with some modifications.展开更多
