Research ArticleOpen accessEvery word in the titleEfficient Classification of Cancer using Support Vector Machines and Modified Extreme Learning Machine based on Analysis of Variance FeaturesA. Bharathi, A.M. NatarajanProblem statement: The primary objective is to propose efficient cancer classification techniques which provide reliable and significant classification accuracy. To achieve this primary research goal is to find the smallest set of genes that can ensure high accuracy in classification using supervised machine learning algorithms. The significance of finding the minimum subset is three fold: (a) The computational burden and … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 22 Oct 2011 · 7,446 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCancer Classification using Support Vector Machines and Relevance Vector Machine based on Analysis of Variance FeaturesA. Bharathi, A.M. NatarajanProblem statement: The objective of this study is, to find the smallest set of genes that can ensure highly accurate classification of cancer from micro array data by using supervised machine learning algorithms. The significance of finding the minimum subset is three fold: The computational burden and noise arising from irrelevant genes are much reduced; the cost for cancer testing … …Journal of Computer Science, Vol. 7, Issue 9 · 25 Jul 2011 · 7,596 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpline Smoothing for Multi-Response Nonparametric Regression Model in Case of Heteroscedasticity of VarianceBudi Lestari, I. Nyoman Budiantara, Sony Sunaryo, Muhammad MashuriProblem statement: Assume that data (yki, tki), k = 1,2,…, p; i = 1,2,…,nk where nk represents the number of repeated measurement of kth object follows multi-response nonparametric regression model with variances of errors are heteroscedastic. Nonparametric regression curves are unknown and assumed to be smooth which are contained in Sobolev space. Random Errors are independent and normally distributed with … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 13 Oct 2012 · 7,960 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMeasuring Drivers’ Effect in a Cost Model by Means of Analysis of VarianceMaria Elena NenniIn this study the author goes through with the analysis of a cost model developed for Integrated Logistic Support (ILS) activities. By means of ANOVA the evaluation of impact and interaction among cost drivers is done. The predominant importance of organizational factors compared to technical ones is definitely demonstrated. Moreover the paper provides researcher and practitioners with useful information to … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 24 Oct 2013 · 6,452 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPhenotypic Evaluation of Heritability, Agro-Morphological and Yield Characters of Sixteen Amaranthus Linn. GenotypesOnuoha Samuel Ogechi, Olawuyi Odunayo JosephThe field experiment was conducted to evaluate the heritability, genetic variance, agro-morphological and yield characters of Sixteen Amaranthus genotypes. The seeds of the sixteen (16) genotypes of Amaranthus evaluated in this study were; NG/AA/MAY/09/027, NG/AA/03/11/010, NG/AO/11/08/042, NG/AO/11/08/039, NG/SA/DEC/07/0423, NG/SA/DEC/07/0412, NGB01667, NGB01601, NGB01283, NGB01271, NGB01276, NGB01259, NGB01644, NGB01234, NGB01613 and NGB01662. The results showed that there were variability performances in growth … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 3 · 3 Aug 2017 · 7,835 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA NOVEL ROBUST AND EFFICIENT TOOL FOR DETECTING HETEROSCEDASTICITYWei Xiong, Maozai TianOne of the greatest values of Quantile Regression (QR) is that it provides a good procedure in the sense that QR could be much more efficient and sometimes arbitrarily more efficient in recovering the mean function than the Least Squares (LS) even when without moment conditions. However, heteroscedasticity definitely causes conditional variances of parametric or nonparametric estimates of mean functions … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 21 Mar 2014 · 6,662 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIs Poisson Dispersion Diluted or Over-Saturated? An Index is Created to AnswerRamalingam ShanmugamA prelude to interpret a pattern in the repeating incidences is to identify the underlying frequency distribution of the collected data. A case in point is the Poisson distribution which is often selected for medical count data such as gene mutations, medication error and number of ambulatory pickups in a day. A requirement for the Poisson distribution is that the … …Current Research in Biostatistics, Vol. 2, Issue 2 · 24 May 2013 · 6,617 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOther Post Employment Benefits-The Other Elephant in the RoomCatherine PlanteThe governments of the fifty states of the United States have made promises to past and present employees regarding retirement benefits-predominately pensions and healthcare coverage. The issues surrounding the pension obligations made to these employees have been well examined but the obligations due to promises of healthcare coverage have not received as much attention. There is great variance among the … …American Journal of Economics and Business Administration, Vol. 4, Issue 2 · 28 Apr 2012 · 7,476 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDemotivating Factors for English Language Learning Among University StudentsReyhaneh Ghadirzadeh, Fariba Pourabolfathe Hashtroudi, Omid ShokriProblem statement: Demotivation is a relatively new issue in the field of second/foreign Language (L2) learning motivation. Recognizing and removing barriers can have a marked effect on motivation and attention to learning in general and ESL/EFL learning in particular. Demotivating factors are essential factors which negatively influence the learner’s attitudes and behaviors and hence lead to undesired learning outcomes. The … …Journal of Social Sciences, Vol. 8, Issue 2 · 21 Feb 2012 · 11,940 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHigh Resolution Satellite Images to Reconstruct Recent Evolution of Domitian CoastlinePasquale Maglione, Claudio Parente, Andrea VallarioIn the last decades, combinations of natural and humanfactors have resulted in extensive morphological changes to our coastlines andin many cases have amplified erosion. In order to limit these changes and theirimpact on coastal zone, it is important toplan specific actions; for this purpose detailed cognizance of coastal zone isnecessary.
