Research ArticleOpen accessPhrase in the titleAbsolute Measures of Interindividual Variation: A Simulation StudyJosé Moral-de la RubiaFour absolute measures and one relative measure of interindividual variability have been defined, together with their point and interval estimation (bootstrap and asymptotic), and an R script has been developed for their computation. However, further simulation studies are required to strengthen their methodological evaluation. This study focused on the three absolute measures with potentially better regularity conditions, Mean Interindividual Differences … …Journal of Mathematics and Statistics, Vol. 22, Issue 1 · 4 Aug 2026 · 957 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEvaluation of Subset Matching Methods: Evidence from a Monte Carlo Simulation StudyLateef Amusa, Temesgen Zewotir, Delia NorthIn the absence or infeasibility of experiments, matching methods have increasingly been used in making causal claims using observational data. This paper conducts a Monte Carlo simulation study, based on a household panel survey, to compare the performance of some widely used subset matching methods. The methods include the propensity score caliper matching, Mahalanobis distance matching, and coarsened exact matching. … …American Journal of Applied Sciences, Vol. 16, Issue 3 · 11 Apr 2019 · 7,740 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleSimulation Study for Evaluating a New Three Stages Procedure for Selecting the Right Multivariate Regression ModelAli Hussein AL-MarshadiProblem statement: This article considers the analysis of multivariate regression experiment that is used frequently in variety of applications research such as psychiatric epidemiologic studies. Our study concerned with multivariate regression model in which the responses were correlated in particular ways for both standard and non-standard multivariate model structures. Our objective is to find reliable procedure that can be used … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 7,814 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Simulation Study of Enhanced Distillation Using Ultrasound Waves for the Separation of Azeotropic MixturesTaha Mahdi, Ammar Emad Al-KawazThe potential of ultrasound waves to enhance distillation system for azeotropic mixture is examined through process flowsheeting using Aspen Plus. Since sonication is not a standard feature in the software library, a mathematical model of the proposed distillation system is developed based on first principles in Aspen Custom Modeler and later exported to Aspen Plus environment for process simulation and … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 2 Jan 2018 · 8,411 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePERFORMANCE OF RIDGE REGRESSION ESTIMATOR METHODS ON SMALL SAMPLE SIZE BY VARYING CORRELATION COEFFICIENTS: A SIMULATION STUDYAnwar Fitrianto, Lee Ceng YikWhen independent variables have high linear correlation in a multiple linear regression model, we can have wrong analysis. It happens if we do the multiple linear regression analysis based on common Ordinary Least Squares (OLS) method. In this situation, we are suggested to use ridge regression estimator. We conduct some simulation study to compare the performance of ridge regression estimator … …Journal of Mathematics and Statistics, Vol. 10, Issue 1 · 3 Jan 2014 · 8,540 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleHydrologic Modeling to Evaluate the Impact of Hydraulic Fracturing on Stream Low Flows: Challenges and Opportunities for a Simulation StudySuresh Sharma, Aashish Shrestha, Colleen E. McLean, Scott C. MartinHydraulic fracturing (fracking) has been increasing in the eastern part of Ohio for the last few years leading to the increased stress on water resources, particularly on the hydrological low flows. Yet, evaluation of the various impacts of fracking on stream low flows using appropriate tools is still a challenging issue, even though significant progress has been achieved in recent … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 7 Aug 2015 · 10,414 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeasibility of Hybrid Neuro-Fuzzy (ANFIS) Machine Learning Model with Classical Multi-Linear Regression (MLR) For the Simulation of Solar Radiation: A Case Study Abuja, NigeriaNajashi B. Gafai, Asia'u Talatu BelgoreThe extremely variable nature of solar radiation makes it difficult for solar power plants to keep up with predicted power output and demand curves. As a result, solar radiation simulation is crucial to the efficient design, administration, and operation of any solar power plant. With only partially satisfactory results, empirical models have been routinely employed in Nigeria to predict solar … …Energy Research Journal, Vol. 13, Issue 1 · 21 Jul 2022 · 10,032 accessesView PDFCite
InvestigationOpen accessEvery word in the titleWLHP Systems in Commercial Buildings: A Case Study Analysis Based on a Dynamic Simulation ApproachGiovanni Barone, Annamaria Buonomano, Cesare Forzano, Adolfo PalomboIn this study, the results of the performance analysis of a WLHP system applied to a large mall building located close to Naples (South Italy) is presented. The investigation was carried out through a purposely developed dynamic simulation model conceived for building-WLHP systems analyses. Through such computer tool, hourly, daily and seasonal system energy, economic and environmental assessments can obtained. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 26 Sep 2016 · 8,208 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFUNCTIONAL SIMULATION PLATFORM FOR STUDYING UNDERWATER RADIATION PATTERNKanwarpreet Gilhotra, Nitaigour Premchand MahalikFor underwater communication, sound signals are used in contrast to RF. Recent development in wireless sensor network for underwater applications such as ocean exploration, marine aquaculture, sea animal tracking and so on have motivated the researchers and developers to understand the properties of sound signal within water in details. This study presents work on design and development of a simulation … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 12 Sep 2014 · 7,850 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSimulation Planning for Sustainable Use of Land Resources: Case study in DiamouDiallo Yacouba, Hu Guangdao, Abdurazak Hussien AbdulahiIn this study, we presented the simulation planning scheme to project land and land resources use changes at a local scale for Diamou (MALI). Problem statement: All the land cover types were under the influence of human and livestock population. Diamou has undergone changes in land-cover over the last decades. The shifting cultivation system practiced was probably the main reason … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,659 accessesView PDFCite
