A hybrid censoring is a mixture of Type I and II censoring. Type I and Type II hybrid censoring models are considered in this work. When n items are placed on a life-test, the experiment terminates under the Type I (Type II) hybrid censoring when either the r-th failure (1=r=n) or the...

After expressing the Fisher information in randomly censored data in terms of hazard rates, we examine the loss of Fisher information under the Koziol-Green random censoring model. Because the same parameter enters both the survival and censoring distributions in this model, the censored data...

We study the maximum likelihood estimation of the dependence parameter of a general bivariate distribution using ranked set sampling. We compare the Fisher information about the dependence parameter in ranked set samples and simple random samples. Results are applied to the bivariate normal and...

On the basis of defining the producers in the supply chain of agricultural products, the SWOT analysis is adopted to analyze the advantages, disadvantages, opportunities and threats of producers in the supply chain of Chinese agricultural products. The paper analyzes the advantages of producers...
