Research ArticleOpen accessIn the abstractA Robust Rescaled Moment Test for Normality in RegressionMd. Sohel Rana, Habshah Midi, A.H.M. Rahmatullah ImonProblem statement: Most of the statistical procedures heavily depend on normality assumption of observations. In regression, we assumed that the random disturbances were normally distributed. Since the disturbances were unobserved, normality tests were done on regression residuals. But it is now evident that normality tests on residuals suffer from superimposed normality and often possess very poor power. Approach: This study … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 8,260 accessesView PDFCite
Research ArticleOpen accessIn the abstractThickness Analysis of Stone Mastic Asphalt (SMA) Slab Compacted Using a Newly Developed Roller CompactorR. Muniandy, F.M. Jakarni, S. Hassim, A.R. MahmudPavement mix design procedures and specifications are usually derived from laboratory experiments. Therefore, laboratory experiments should be able to simulate to a high degree the conditions in the field, especially in term of compaction procedures. Based on literature reviews and analysis of past studies, it can be concluded that there are no exact method for laboratory compaction that can simulate … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Environmental Performance-HSEQ Management System, Regarding the International and Iranian Oil and Gas General ContractorsJ. Nouri, M. Abbasspour, E. Roayaei, H. NikoomaramThe ever-increasing significance of the health, safety, environment and quality Management system has led general contractors including those involved in the oil and gas industry to place the implementation of this integrated system on their agenda, in a way that the implementation and execution of this system is considered as one of their operation and development strategies. The purpose of … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,085 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordDetection and Diagnostic Approach of COVID-19 Based on Cough Sound AnalysisMuzhir Shaban Al-Ani, Thabit Sultan Mohammed, Awni Ismail Sultan et al.Coronavirus (COVID-19) started at the end of 2019 and then spread out around the world as a pandemic at the beginning of 2020. At that time, researchers began to work on detecting and diagnosing this virus, where many methods have been applied for this reason. This study focuses on how to diagnose coronavirus through patients’ cough. Accordingly, real samples were … …Journal of Computer Science, Vol. 17, Issue 6 · 29 Jun 2021 · 7,803 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMODEL BUILDING FOR AUTOCORRELATED PROCESS CONTROL: AN INDUSTRIAL EXPERIENCEM. A. Djauhari, S. L. Lee, Z. IsmailWe show that many time series data are governed by Geometric Brownian Motion (GBM) law. This motivates us to propose a procedure of time series model building for autocorrelated process control that might consist of two steps. First, we test whether the process data are governed by GBM law. If it is affirmative, the appropriate model is directly given by … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 29 Mar 2014 · 6,624 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOn Three-Way Unbalance Nested Analysis of VarianceSmaila S. Sanni, Eugene C. UkaegbuProblem statement: In this study, we give a simple analytically tractable procedure for solving three-way unbalanced nested Analysis of Variance (ANOVA). In many realistic situations, unbalanced design was unavoidable due to natural constraints and missing data. Approach: Here, we present a comprehensive approach for addressing solutions of problems arising from unbalanced nested ANOVA. We consider the F-statistics under the different … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 10 Dec 2011 · 7,717 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDeveloping an Anthropometric Database for Saudi Students and Comparing Saudi Dimensions relative to Turkish and Iranian PeoplesMohamed A.A. MansourThe main objectives are to develop an anthropometric database for Saudi Students and to compare it relative to two other Middle Eastern people. A national anthropometric standard for Saudis does not exist and few studies have focused on the development of Saudis anthropometric data and the comparison of them with other races. The availability of these data is necessary to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 24 Jun 2016 · 10,201 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSELECTING THE COVARIANCE STRUCTURE IN MIXED MODEL USING STATISTICAL METHODS CALIBRATIONAli Hussein AL-MarshadiIn this article the analysis of experiment of repeated measures design is considered which is used often in different fields of studies. In order to analyze the experiment of repeated measures design efficiently we need to select the suitable covariance structure which required a lot of efforts. In the current paper an approach is used to guide the selection of … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 8 Jul 2014 · 7,222 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordApplication of a Statistical Model to Biological Data Analysis: Exclusive BreastfeedingNaushad Mamode Khan, Cheika Jahangeer, Daya Goburdhun, Maleika Heenaye-Mamode KhanProblem statement: Breastfeeding is of utmost importance in the maternal life of a woman, particularly exclusive breastfeeding. Exclusive breastfeeding during the first 6 months of life supports optimal growth and development during infancy and reduces the risk of obliterating diseases and problems. Many probability distributions were proposed to model such data such as the mixed Poisson distributions. However, the estimation … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 10,818 accessesView PDFCite
