Research ArticleOpen accessEvery word in the titleExponential Smoothing Method of Base Flow Separation and Its Impact on Continuous Loss EstimatesGurudeo Anand Tularam, Mahbub IlaheeThe calculation of loss is vital for design flood estimation models and in order to estimate continuing loss (CL), proportional loss (PL) and volumetric runoff coefficient, the surface runoff has to be separated from the total given in a stream flow hydrograph. To obtain the volume of surface runoff from the streamflow hydrograph, baseflow separation becomes necessary and in this … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 8,484 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAPPROXIMATION OF ESTIMATES IN THE SUSCEPTIBLE-INFECTIOUS-REMOVED EPIDEMIC MODELChanghyuck OhIn this note, a simple approximation for the maximum likelihood estimates of infection and removal parameters used in the Susceptible-Infectious-Removed (SIR) epidemic model is presented. This approximation can be applied when the numbers of susceptible and infected individuals are observable only at discrete points in time. Since, in such cases, a closed form of the likelihood function is generally too … …Journal of Mathematics and Statistics, Vol. 9, Issue 1 · 21 Mar 2013 · 6,760 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAgronomic and Economic Parameter Estimates of Cocoyam as Influenced by Fertilizer and EnvironmentPrince Emmanuel Norman, Yvonne Sylvia Gloria Ethel Norman, Jenneh Fatima BebeleyThe effects of fertilizer and environment on agronomic traits and economic parameters in cocoyam were assessed at the Njala Agricultural Research Centre experimental site during the 2014/2015 and 2015/2016 cropping seasons. The fertilizer types used were 200 kg ha–1 NPK 15-15-15, 2000 kg ha–1 Rabbit Manure (RM), and no fertilizer (control). The trial was established in the open field and … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 24 Nov 2022 · 6,049 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProbabilistic Estimates of the Largest Strictly Convex Singular Values of Pregaussian Random MatricesYang LiuIn this study, the p-singular values of random matrices with Gaussian entries defined in terms of the lp-p-norm for p>1, as is studied. Mainly, using analytical techniques, we show the probabilistic estimate, precisely, the decay, on the upper tail probability of the largest strictly convex singular values, when the number of rows of the matrices becomes very large and the … …Journal of Mathematics and Statistics, Vol. 11, Issue 1 · 6 May 2015 · 6,887 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAsymptotic Properties of Spectral Estimates of Second-Order with Missed ObservationsG. S. Mokaddis, M. A. Ghazal, A. E. El-DesokeyProblem statement: As a complement of the periodogram study the asymptotic properties of the spectral density using data window for stationary stochastic process are investigated. Some statistical properties of covariance estimation function with missing observations are studied. Approach: The asymptotic normality was discussed. A numerical example was discussed by using computer programming. Results: The study of time series with missed … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,496 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Simulation Model Estimates of the Intercropping Advantage of an Immature-Rubber, Banana and Pineapple SystemMohamadu Boyie Jalloh, Wan Sulaiman Wan Harun, Jamal Talib et al.Problem statement: Intercropping has been shown to have many advantages but it is fallacious to conclude it is always a better cropping system. Little is known about a new double-hedgerow intercropping of rubber, banana and pineapple in relation to its effects on growth and yield of the component crops when compared to their monocrops. Simulation modeling offers a cheaper and … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,003 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBoosted Regression Estimates of Spatial Data: Pointwise InferenceMarco Di Marzio, Charles C. TaylorIn this study simple nonparametric techniques have been adopted to estimate the trend surface of the Swiss rainfall data. In particular we employed the Nadaraya-Watson smoother and in addition, an adapted-by boosting-version of it. Additionally, we have explored the use of the Nadaraya-Watson estimator for the construction of pointwise confidence intervals. Overall, boosting does seem to improve the estimate as … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,349 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCost Efficiencies and Rankings of Flagship UniversitiesG. Thomas SavProblem statement: Each state in the U.S. touts a premier university as the flagship of its publicly funded higher education system. With decreased government budgets and increased interest in public management reforms, these institutions are being pressured to provide evidence of and set examples for ever greater improvements in operating cost efficiencies. The problem, however, is that empirical measures of … …American Journal of Economics and Business Administration, Vol. 3, Issue 4 · 20 Jan 2012 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHow Youth in India and Lebanon Rate their IntelligenceRamzi Nasser, Sushila SinghalA sample of 648 Lebanese and 252 Indian students estimated their intelligences based on Gardner's 10 multiple intelligence. Males rated higher their body kinesthetic and religious dimension (spiritual) while females rated higher their verbal and intra-personal estimates of intelligence. Using the educational level of the parent, no significant correlation with self-estimates of intelligence for each of the national samples was … …Journal of Social Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,095 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStatistical Tool for Testing Agreement Level on Continuous DatasetsBasavarajaiah Mariyappa Doddagangavadi, B. Narasimha Murthy, Netra RajpurohitVarious analytical studies explored the new innovation for testing agreement level in medical and life sciences which can be simulated by Cohen ‘κ’ based on the practical applications. From the past medical literature, many authors suggested that, there is some disproportion research gaps that exists in the statistical methods for measuring the agreements between two or more observers from ‘Cohen … …Current Research in Biostatistics, Vol. 11, Issue 1 · 19 May 2021 · 11,780 accessesView PDFCite
