A number of methods have been established to estimate the proportion true null hypotheses in multiple testing under the assumption of independency. On other hand, the test statistics are either discrete or continuous. In this paper, we will review an existing likelihood approach for estimating the proportion of true nulls controlling the false discovery rates when the test statistics are continuous (see Hualing and Hanfeng, 2021). We therefore present an extension of...
This study aimed to search for a solution to linear partial differential equations, which represent many physical and engineering phenomena, and which only appear in the form of mathematical systems that describe the nature of these phenomena. The focus here was on the Laplace equation in the second dimension, as a model for describing these phenomena using the finite difference method. To approximate the solution of these equations, the equation is converted to another form, so that a...

The study sought to explore the impact of the approved approach of application of Lean and Six Sigma, which focuses on improving quality and reducing lead-time, and removing waste in the supply chain. As this integration of both applications is suitable for small and medium-sized companies (SMEs), the manager of company X wishes to solve its problems in lead time and transportation costs. The paper used the application of Lean and Six Sigma within the DMAIC stages.(define, measure, analyse,...
The burgeoning field of genomics has reinvigorated interest in multiple-testing methods as it introduces new methodological and computational challenges. Whole genome microarray studies (e.g., differential expression, differential methylation, ChIP-chip) offer the possibility to test millions of traits in one genome. This article discusses the preterment of Adjusted likelihood approach and Average estimate approach (see Ewhida, Alammari and Ihwil, 2022; Jiang and Doerge, 2008) for estimating...
