Al-KhaldiThe analysis of the educational attainment by Gender tells us about the general demand for education and qualitative change both in population and labor force. The term educational attainment used here refers to the actual level of education completed by a person as it is superior to the enrolment ratio - as a proxy for educational attainment - especially for … …Journal of Social Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 8,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch Note: Standard Scores Based on the Median and Inter-quartile RangeJames CarifioRecently when asked to help with statistical analyses of the Medicare Provider Analysis and Review (MEDPar) Data, I encountered a common statistical and analytical problem with this national database, which is also common to many national and health databases. This problem was the problem of extremely skewed distributions (g1 and/or g2 typically exceeding 20), which creates numerous difficulties in comparing … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 6,840 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpidemiologic Assessment of the Protective Effects of Smallpox VaccinationHiroshi Nishiura, Isao Arita, Markus Schwehm, Martin EichnerDespite smallpox eradication, the widely discussed possibility of a bioterrorist attack using a variola virus makes it necessary to review the epidemiology of smallpox and the effects of various vaccination schemes. This paper provides a literature review concerning the epidemiologic assessment of the protective effects of smallpox vaccination, with particular emphasis on the statistical and theoretical points of view. Although … …American Journal of Infectious Diseases, Vol. 2, Issue 1 · 31 Mar 2006 · 7,010 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Meaning of a Redundant Codon: There is Protein Folding Information in Nucleic Acids in Addition to the Genetic CodeJan C. Biro, Josephine M.K. BiroAll the information necessary for protein folding is supposed to be present in the amino acid sequence. It is still not possible to provide specific ab initio structure predictions by bioinformatical methods. It is suspected that additional folding information is present in protein coding nucleic acid sequences, which is not represented by the known genetic code. Nucleic acid subsequences comprising … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 1 · 31 Mar 2006 · 8,292 accessesView PDFCite

Research ArticleOpen accessIn the abstractSplitting Technique Initialization in Local PCAAlok Sharma, Kuldip K. Paliwal, Godfrey C. OnwuboluThe local Principal Component Analysis (PCA) reduces linearly redundant components that may present in higher dimensional space. It deploys an initial guess technique which can be utilized when the distribution of a given multivariate data is known to the user. The problem in initialization arises when the distribution is not known. This study explores a technique that can be easily … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,719 accessesView PDFCite

MardiaIn response to the drought experienced in Southern Italy a rain seeding project has been setup and developed during the years 1989-1994. The initiative was taken with the purpose of applying existing methods of rain enhancement technology to regions of south Italy including Puglia. The aim of this study is to provide statistical support for the evaluation of the experimental … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractParsimonious Var Models For Air Pollution Dynamic AnalysisFontanella lara, Granturco mariagraziaWe discuss a framework to obtain temporal predictions for an evolving spatial field regularly sampled in time at arbitrary spatial locations. Difficulties caused by large data sets and the modelling of complicated spatio-temporal interactions limit the effectiveness of traditional space-time statistical models. In this study, we propose the use of a flexible approach to deal with large and small time-scale … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,181 accessesView PDFCite
