Research ArticleOpen accessIn the abstractParameter Estimation and Determination of Sample Size in Logistic RegressionAdeleke Kazeem Adedayo, Dawud Adebayo AgunbiadeThe determination of Sample-Size is often an important step in planning a statistical study and it is usually a difficult task. Among the important hurdles to be surpassed, one must obtain an estimate of one or more error variances and specify an effective sample size of importance. The study was carried out to check for the estimation of parameter and … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 4 Feb 2013 · 6,918 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation and Analysis of Output Gap: An Application of Structural Vector Autoregression and Hodrick-Prescott-FmethodsSaeed Dehghan Khavari, Seyed Hossein MirjaliliIn this study we examined output gap in the Iranian economy. The main question of the study is that how much is seasonal output gap in Iranian Economy and which factor affects gap variation. The other question is that whether using HP-F as a statistical based method for estimating output gap, provide different result than using SVAR as theory based … …American Journal of Economics and Business Administration, Vol. 4, Issue 3 · 27 Aug 2012 · 7,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeptospirosis in the Tropics: When Prevention Doesn't Easily Sell as a Ton of CureRoger Lee MendozaProblem statement: Human leptospirosis -- the most widespread zoonotic disease -- thrives in tropical and subtropical climates. It is seldom addressed ex ante or prior to an outbreak or expected outbreak by governments of high-risk countries. Whether common, post-exposure treatment with antimicrobial drugs is more cost-efficient than reducing animal reservoir populations was the overarching question that guided this study. A … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 8,381 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Optimization with Multilayer Perceptron Neural Network and Using New Pattern in Decision Tree ComparativelyMurat Kayri, Omay CoklukProblem statement: The aim of the present study is to exemplify the use of Artificial Neural Networks (ANN) for parameter prediction. Missing value or unreal approach to some questions in scale is a problem for unbiased findings. To learn a real pattern with ANN provides robust and unbiased parameter estimation. Approach: To this end, data was collected from 906 students … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Convergence-Confinement Method: Roles and Limits in Modern Geomechanical Tunnel DesignPierpaolo OresteThe convergence-confinement method, based on the analysis of the stress and strain state that develops in the rock around a circular tunnel, has been presented in this study with the two analytical solutions that have been most frequently used in recent years. Problem statement: Thanks to the increased power of electronic processors and the spread of numerical methods, the role … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 10,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Performance of Latent Root-M based RegressionHabshah Midi, Lau Ung HuaProblem statement: In the presence of multicollinearity, the estimation of parameters in multiple linear regression models by means of Ordinary Least Squares (OLS) is known to suffer severe distortion. An alternative approach was to use the modified OLS which was based on the latent roots and latent vectors of the correlation matrix of the independent and dependent variables. This procedure … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 8,657 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Severity of Mitral Valvular Regurgitation with Doppler Echocardiography Using Proximal Flow Convergence MethodPinjari Abdul Khayum, M.N. Giriprasad, P.V. SrideviProblem statement: Valvular regurgitation is recognized as the central cause of morbidity and mortality. Even though the clinician can detect the presence of regurgitation by mere physical examination; diagnostic methods become inevitable while estimating the severity of valvular regurgitation and in the transformation of cardiac chambers as in reaction to the volume overload condition. Lately, a promising new technology, the … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Comparison of Spectrophotometric Method and High-Performance Liquid Chromatography in Photosynthetic Pigments AnalysisSabina Jodłowska, Adam LatałaProblem statement: Spectrophotometric method and High-Performance Liquid Chromatography (HPLC) are the most useful tools to photosynthetic pigments analysis. The main objective of this reaserch was to compere the results obtained by these two independent methods in experiments under controlled laboratory conditions. Approach: Comparison between spectrophotometric and HPLC methods for pigment analysis was carried out on Baltic cyanobacterium Geitlerinema amphibium, which … …OnLine Journal of Biological Sciences, Vol. 11, Issue 2 · 30 Sep 2011 · 10,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractApproximation of Iteration Number for Gauss-Seidel Using Redlich-Kister PolynomialM. K. Hasan, J. Sulaiman, S. Ahmad et al.Problem statement: Development of mathematical models based on set of observed data plays a crucial role to describe and predict any phenomena in science, engineering and economics. Therefore, the main purpose of this study was to compare the efficiency of Arithmetic Mean (AM), Geometric Mean (GM) and Explicit Group (EG) iterative methods to solve system of linear equations via estimation … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 8,143 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Statistical Procedures for Analysis of Genetic Diversity in Domestic Animal PopulationsM. R. Nassiry, A. Javanmard, Reza TohidiProblem statement: A wide range of studies for the assessment of genetic diversity in livestock breed were conducted using genetic distance. For high-accuracy and unbiased estimation sampling methods, criteria of choosing type of DNA markers, distance measurement strategies, cluster analysis will be important for any genetic diversity projects. Approach: Main objective of this short review is focusing on application statistical … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 7,652 accessesView PDFCite
