Research ArticleOpen accessIn the keywordsNote on the Comparison of Some Outlier Labeling TechniquesN. P. OlewueziProblem statement: Methods proposed for estimating and resolving outliers are compared. Approach: In this respect, we exploit three well-known classifiers for identifying outliers to establish guidelines for the choice of outlier detection methods. Results: It was shown that the standard deviation is inappropriate to use here because it is highly sensitive to extreme values. Conclusion/Recommendations: The result of these estimated … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 18 Nov 2011 · 8,261 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Inverse Weibull Distribution: Properties and ApplicationsMona Mustafa Elbiely, Haitham M. YousofIn this work, we introduce a new flexible extension of the Inverse Weibull distribution. Some important mathematical properties of the proposed model are derived along with a numerical analysis of mean, variance, skewness and kurtosis measures of the proposed model. The performance of the maximum likelihood method is assesses via a comprehensive simulation studies in terms of mean squared errors. … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 25 Mar 2019 · 7,506 accessesView PDFCite

Research ArticleOpen accessIn the abstractOligoasthenoteratozoospermia and Necrozoospermia: A Study of Sperm Na+, K+-ATPase α4 and Plasma Membrane Ca2+-ATPase 4 RegulationSilvia W. Lestari, Dessy Noor Miati, AsmarinahThe oligoasthenoteratozoospermia (OAT) and necrozoospermia are the extreme sperm abnormalities in male infertility. These sperm abnormalities may be related to the imbalance of ion transport which mediated by the ion-transporting P-type ATPases, such as Na+, K+-ATPase and Ca2+-ATPase. Until now, there is limited data about the activity of Na+, K+-ATPase and Ca2+-ATPase in sperms in the OAT and necrozoospermia samples. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 3 Aug 2018 · 11,269 accessesView PDFCite
