Research ArticleOpen accessEvery word in the titleSurvival Analysis of Data of HIV Infected Persons Receiving Antiretroviral Therapy Using a Model-Based Binary Tree ApproachSimon Tiendrébéogo, Blaise Somé, Séni Kouanda, Simplice Dossou-GbétéDiscrete-time approach is used in survival data analysis when only the time interval in which the event of interest has occurred is known or when this event occurs in a discrete - time scale. The work presented in this paper is motivated by the analysis of HIV/AIDS follow-up data collected in Burkina Faso during the 5-YEAR Global Fund program implemented … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 24 Dec 2019 · 6,495 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCombining Model-Based Testing and Failure Modes and Effects Analysis for Test Case Prioritization: A Software Testing ApproachAtifi Meriem, Marzak AbdelazizDue to The complexity of modern software projects and the increasing size of software systems, it becomes difficult to manually perform tests with limited resources. Also, manual testing cannot assure that the software is tested using all possible combinations of inputs. Therefore, automate software testing activities have become primordial in the Software Development Life Cycle (SDLC). Model-based testing is a … …Journal of Computer Science, Vol. 15, Issue 4 · 4 Apr 2019 · 8,216 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResidual Analysis for Auto-Correlated Econometric ModelHabib Ahmed ElsayirThe aim of this article is to provide residual analysis for a time series data of Gross Domestic Product (GDP) of the Sudan. An econometric time series model with macroeconomic variables is conducted to examine the goodness of fit using residual. Many statistical tests are used in time series models in order to make it a stationary series. After applying … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 1 Jun 2019 · 6,577 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Application of Multivariate Analysis in Modeling Students Placement in Nigerian Higher InstitutionsAli Idrisa Gambo, Mohammed Waziri YusufProblem statement: Students’ placement into courses of study in most (if not all) tertiary institutions in Nigeria had long been a problematic exercise. Most students get placed into courses of study they are ill suited to and then for which they are ill prepared. Approach: This research focused on the polytechnic, taking the newest federal polytechnic as a case study, … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,289 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDividend Maximization in the Cramer-Lundberg Model using Homotopy Analysis MethodJuma Kasozi, Fred Mayambala, Charles Wilson MaheraProblem statement: We used the Homotopy Analysis Method (HAM) to numerically compute the value function of the dividend payment in the basic insurance process. Approach: The process is a constant income stream from premiums which is subtracted a claim process of the Poisson type. Further, an allowance for payment of dividends to share holders was incorporated. Results: The case when … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 31 Jan 2011 · 7,018 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleComparative Analysis of Topic Modeling on People Query-Based DataSaranya M, Amutha BAs using the internet becomes more common in our daily lives, Perhaps greater numbers of individuals are buying things digitally. Specialized digital marketplaces for things like clothes and books have turned into megastores with many stores. This makes it harder to find what you're looking for and takes more time.
