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 keywordsEconomic Growth and Unemployment: An Empirical AnalysisFuad M. KreishanProblem statement: This research investigates the relationship between unemployment and economic growth in Jordan through the implementation of Okun’s law. Approach: Using annual data covering the period 1970-2008, time series techniques are used to test the relation between unemployment and economic growth and to obtain estimates for Okun’s coefficient. Namely, the study used Augmented Dickey-Fuller (ADF) for unit root, cointegration … …Journal of Social Sciences, Vol. 7, Issue 2 · 21 Mar 2011 · 12,609 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPredicting Insurance Investment: A Factor Analytic ApproachSamuel Obi-Nnamdi Agwuegbo, Adetunji Philip Adewole, A. N. MaduegbunaProblem statement: In the last decade growing attention has been paid to the pattern of investments by the insurance industry and the question of how to evaluate such investments. In an economy where the capital market is huge and active, mathematical considerations come into play in the selection of investments to ensure yield maximisation. Approach: This study examined the use … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,498 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Distribution-Free Bayesian Approach for Indirect ComparisonsJohanna S. van Zyl, Jack D. TubbsThe objective of this paper is to consider an indirect comparison between treatments B and C when each have been compared directly to treatment A in separate studies. Problems of this type are common in Network Meta-Analysis (NMA). A commonly used method assumes that the underlying data, Y, are normally distributed and µ = E(Y) is the measure of clinical … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 3 Jul 2019 · 6,687 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Impact of a Letter of Map Amendment on Floodplain Property ValueJames E. LarsenSubstantial empirical evidence indicates properties across the United States that are located within a Special Flood Hazard Area (SFHA) sell at a discount compared to similar properties otherwise located. This result is also true in our sample. Researchers have suggested the price discount equals a combination of the present value of the required flood insurance premiums and the value of … …American Journal of Economics and Business Administration, Vol. 4, Issue 3 · 14 Aug 2012 · 6,894 accessesView PDFCite
