Research ArticleOpen accessPhrase in the titleRobust Estimations as a Remedy for Multicollinearity Caused by Multiple High Leverage PointsArezoo Bagheri, Habshah MidiProblem statement: The Least Squares (LS) method has been the most popular technique for estimating the parameters of a model due to its optimal properties and ease of computation. LS estimated regression may be seriously disturbed by multicollinearity which is a near linear dependency between two or more explanatory variables in the regression models. Even though LS estimates are unbiased … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 8,247 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTwo-Step Robust Diagnostic Method for Identification of Multiple High Leverage PointsArezoo Bagheri, Habshah Midi, A.H.M. Rahmatullah ImonProblem statement: High leverage points are extreme outliers in the X-direction. In regression analysis, the detection of these leverage points becomes important due to their arbitrary large effects on the estimations as well as multicollinearity problems. Mahalanobis Distance (MD) has been used as a diagnostic tool for identification of outliers in multivariate analysis where it finds the distance between normal … …Journal of Mathematics and Statistics, Vol. 5, Issue 2 · 30 Jun 2009 · 8,306 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHigh-Dose Vitamin D3 Intake Is Associated with Decreased Symptoms of Multiple SclerosisMichelle L. Steinwart, David M. DuriancikMultiple sclerosis (MS) is one of the most widespread disabling autoimmune neurological conditions of adults between the ages of 20 and 40 globally. Medical researchers do not completely understand the possible causes of MS, nor have they determined the rate of progression. A limited number of clinical trials conducted in recent years have explored the link between vitamin D deficiency … …American Journal of Immunology, Vol. 14, Issue 1 · 4 Sep 2018 · 9,283 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIndoor Characterisation using High-Resolution Signal Processing Based on Five-Port Techniques for Signal Input Multiple Output SystemsSmari Mouheddin, Bel hadj Taher JamelProblem statement: The development of wideband mobile communication systems requires a deep knowledge of the characteristics of the indoor mobile radio channel. The characterization of the indoor multi-path propagation structure is important in developing antifading techniques for high-speed digital radio access. The high-resolution of the estimation of the Time of Arrival (ToA) and the Direction of Arrival (DoA) of multi-path … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,684 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Efficient Implementation of Re-Sampling Technique for High Performance Multiple Classifier SystemsS. Sathiyabama, K. Thyagarajah, D. AyyamuthukumarDue to the large size of the database, the entire training dataset could not be used to construct the classifiers. One popular solution is to separate stream data into chunks, learn a base classifier from each chunk and then integrate all base classifiers to form Multiple classifier system (MCS). Sometimes this data streams does not include all the classes in … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,014 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEstimation Methods for Multicollinearity Proplem Combined with High Leverage Data PointsMoawad El-Fallah, Abd El-SallamProblem statement: Least Squares (LS) method has been the most popular method for estimating the parameters of a model due to its optimal properties and ease of computation. LS estimated regression may be seriously affected by multicollinearity which is a near linear dependency between two or more explanatory variables in the regression models. Although LS estimates are unbiased in the … …Journal of Mathematics and Statistics, Vol. 7, Issue 2 · 18 May 2011 · 7,617 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHigh Pitch Delay Resolution Technique for Tonal Language Speech Coding Based on Multi-Pulse Based Code Excited Linear Prediction AlgorithmSuphattharachai ChomphanProblem statement: In spontaneous speech communication, speech coding is an important process that should be taken into account, since the quality of coded speech depends on the efficiency of the speech coding algorithm. As for tonal language which tone plays important role not only on the naturalness and also the intelligibility of the speech, tone must be treated appropriately. Approach: … …Journal of Computer Science, Vol. 7, Issue 1 · 14 Jan 2011 · 6,729 accessesView PDFCite
Research ArticleOpen accessIn the keywordsApplication of Theories of Complexity and Chaos to Economic MisgovernancePartha Gangopadhyay, Nasser Elkanj, Mustafa A. RahmanProblem statement: In this study we develop a comprehensive model involving local taxes, intergovernmental transfers and bureaucratic corruption to characterize a fiscal equilibrium in order to explain the provision of local (public) expenditure in developing nations. The main goal of the research is to explain economic misgovernance as an equilibrium phenomenon, which is therefore expected to persist over time despite … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 27 Jul 2011 · 7,375 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTransformation or Transgression? Institutional Habitus andWorking Class Student IdentityTina Byrom, Nic LightfootProblem statement: Whilst evidence continues to highlight disparity in Higher Education (HE) participation rates across social groups, there continues to be small numbers of young people from social groups 4-7 choosing to go to university. However, university experience varies across the different social groups and differing social positions appear to influence the higher education institution students apply to and secure … …Journal of Social Sciences, Vol. 8, Issue 2 · 18 Feb 2012 · 9,615 accessesView PDFCite
Research ArticleOpen accessIn the abstractIAFIR Optimization against NOMA Competitors: A Comprehensive Analysis on Energy-Efficient Non-Orthogonal Multiple AccessS. Pavithra, S. ChitraThe ever-growing demands of next-generation wireless networks necessitate the exploration of innovative technologies to enhance spectral efficiency, user experience and network performance. Non-Orthogonal Multiple Access (NOMA) has emerged as a promising candidate, offering the potential for increased capacity and improved system reliability. NOMA allows multiple users to share the same time-frequency resource, breaking away from traditional orthogonal access methods.
