Research ArticleOpen accessEvery word in the titleThe Estimation of Logistic Probability Model of Binomial Data: Simulation ComparisonZaki. J. Al- Sarraf, Faris M. Al- Athari, Hilmi F. KittaniProperties of various types of estimators of the regression coefficients in linear logistic regression models were considered. The estimators include those based on maximum likelihood, minimum chi-square and weighted least squares. The results of a large scale simulation investigation evaluating the moment properties of the estimators are presented for the case of logistic model with a single explanatory variable. …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 6,690 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA General Probability Distribution Using Burmann Power SeriesRichard F. Patterson, Pali SenThe goal of this study is to present a general power series distribution that exhibits the properties of some well known distributions. To accomplish this goal we examine an infinite sequence of independent random variables having a Bürmann’s power series distribution. Consequently, we derive moment generating function of the distribution and establish the maximum likelihood estimate of the component that … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,290 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnhanced Hybrid Spectrum Sensing Method Using TCDT and IEDT for Cognitive RadioNeha Chaudhary, Rashima Mahajan, Richa Adlakha et al.The development of efficient spectrum sensing techniques has witnessed progressive growth for optimum utilization of spectrum resources in cognitive radio. The primary objective of spectrum sensing is the identification and proper utilization of the spectrum holes. Nowadays, due to the advancement of wireless technologies, the demand for spectrum is also increasing and thus in turn, the requirement for better spectrum … …Journal of Computer Science, Vol. 20, Issue 11 · 20 Nov 2024 · 4,301 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCross-Layer Design for Combining Adaptive Modulation and Coding with DMMPP Queuing for Wireless NetworksManikandan Arunachalam, Naresh Kumar Babu, Anandan Perumal et al.Resource management and Quality of Service (QoS) are seen as key concerns for many applications in 5G networks since they support millions of linked devices. When sharing information over error-prone wireless networks, these resource management strategies are necessary to fulfill multimedia applications with a minimum throughput guarantee, low error probability, and high tolerated delay. One of the most complex traffic … …Journal of Computer Science, Vol. 19, Issue 6 · 31 May 2023 · 5,419 accessesView PDFCite
Research ArticleOpen accessIn the keywordsModification on PPS Sample Scheme with ReplacementAyed R.A. Alanzi, Naser A. Alodat, Ahmad M. QazzaIn this paper we have developed an alternative estimator for the Probability Proportional to Size (PPS) with replacement sampling scheme when certain characteristics under study are positively correlated with the selection probability. An analogue to the well-known superpopulation model for finite population is also suggested, using which, we compare the proposed estimator with Hansen and Hurwitz estimator. Finally, an empirical … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 19 Jun 2019 · 7,188 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImprovement of Bayesian Credible Interval for a Small Binomial Proportion Using Logit TransformationToru Ogura, Takemi YanagimotoA novel credible interval of the binomial proportion is proposed by improving the Highest Posterior Density (HPD) interval using the logit transformation. It is constructed in two steps: first the HPD interval for the logit transformation of the binomial proportion is driven and then the corresponding credible interval of the binomial proportion is calculated by the inverse logit transformation of … …Current Research in Biostatistics, Vol. 8, Issue 1 · 20 Nov 2018 · 7,978 accessesView PDFCite
Research ArticleOpen accessIn the keywordsManagement of Effective Factors in Components’ Supply Chain on Losses of Electric Distribution SystemM. Esmaeil Honarmand, M. Sadegh Ghazizadeh, Ali KermanshahRestructuring in the electrical distribution utilities, the loss management is one of the critical activities to enhance network efficiency. Accordingly, management of technical loss would be the main target of the asset managers. For loss management, the usual methods of loss calculation and estimation need numerous data which is not used to real networks. In this research, a practical method … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 21 Apr 2018 · 7,551 accessesView PDFCite
Research ArticleOpen accessIn the keywordsModeling of Rainfall Characteristics for Monitoring of the Extreme Rainfall Event in Makassar CityWahidah Sanusi, Usman Mulbar, Hendra Jaya et al.Flooding is a common problem that occurs in some regions of Indonesia, including Makassar city. In the planning of flood control, rainfall variables are very necessary as the frequency, intensity and duration of rainfall. The relationship of these variables can be expressed in a curve Intensity-Duration-Frequency (IDF). The objectives of this study are to identify the best fitting distribution of … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 10 Apr 2017 · 7,797 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProbabilistic 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 accessIn the keywordsECONOMIC EVALUATION OF AQUACULTURE INVESTMENTS UNDER CONDITIONS OF RISK AND UNCERTAINTY IN THE MEDITERRANEAN SEAFilippo Sgroi, Salvatore Tudisca, Anna Maria Di Trapani, Riccardo TestaThis study aims to analyze, from a technical and economic point of view, the choice between alternative investments in aquaculture under conditions of risk and uncertainty. In particular, a comparative analysis has been conducted between an inshore and an offshore farm producing European sea bass in the Mediterranean Sea. The applied model refers to the theory of subjective probability, assigning … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 1 Oct 2014 · 6,897 accessesView PDFCite
