Research ArticleOpen accessIn the keywordsDistinguishing Congestion and Technical Inefficiency in Presence Undesirable OutputFaranak Hosseinzadeh Saljooghi, Mohammad Mahallati RayeniProblem statement: This study focuses on problems of congestion and how they might be treated in universities, also investigates a methodology to measure undesirable outputs congestion in addition to inputs congestion, from both theoretical and empirical perspectives. Congestion indicates an economic state where inputs are overly invested. Evidence of congestion occurs whenever reducing some inputs can increase outputs. Approach: The … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 2 Aug 2011 · 7,372 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Integrated Weed Management on Yield and Yield Component of Bread Wheat in Guji Zone, Southern OromiaLulu Misgana, Yared Tesfaye, Dagne Abu et al.Bread wheat (Triticum aestivum L.) is one of the most important food crops in the world, providing a staple food for over 35% of the global population; in Ethiopia, however, production in highland regions like the Guji zone is severely constrained by heavy weed infestation, causing significant yield gaps. While Integrated Weed Management (IWM) is a promising solution, locally validated … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 5 Dec 2025 · 3,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Alpha-Exhaustive Multiple Testing ProcedureMark Chang, Xuan Deng, John BalserA multiple testing procedure can be a single-step procedure such as Bonferroni's method or a stepwise procedure such as Hochberg's stepup method and Hommel's method. It can be an α-exhaustive or α-conservative approach. We develop a single α-exhaustive procedure that can improve power 2-5% over Hochberg's and Hommel's methods in common situations when the test statistics are mutually independent. The … …Current Research in Biostatistics, Vol. 6, Issue 2 · 30 Jun 2017 · 8,095 accessesView PDFCite

Research ArticleOpen accessIn the abstractGAUSSIAN COPULA MARGINAL REGRESSION FOR MODELING EXTREME DATA WITH APPLICATIONSutikno, Heri Kuswanto, Iis Dewi RatihRegression is commonly used to determine the relationship between the response variable and the predictor variable, where the parameters are estimated by Ordinary Least Square (OLS). This method can be used with an assumption that residuals are normally distributed (0, σ2). However, the assumption of normality of the data is often violated due to extreme observations, which are often found … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 4 Apr 2014 · 7,620 accessesView PDFCite
