Research ArticleOpen accessPhrase in the titleBootstrap Method for Dependent Data Structure and Measure of Statistical PrecisionT. O. Olatayo, G. N. Amahia, T. O. ObiladeProblem statement: This article emphasized on the construction of valid inferential procedures for an estimator θ^ as a measure of its statistical precision for dependent data structure. Approach: The truncated geometric bootstrap estimates of standard error and other measures of statistical precision such as bias, coefficient of variation, ratio and root mean square error are considered. Results: We extend it … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,258 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleLossy Asymptotic Equipartition Property for Networked Data StructuresKwabena Doku-AmponsahIn this study, we prove a Generalized Information Theory for Networked Data Structures modelled as random graphs. The main tools in this study remain large deviation principles for properly defined empirical measures on random graphs. To motivate the paper, we apply our main result to a concrete example from the field of Biology. …Journal of Mathematics and Statistics, Vol. 13, Issue 2 · 24 May 2017 · 6,979 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Machine Learning Models to Predict Student Academic Performance Using Structured Educational DataHardik Ishwarbhai Patel, Dharmendra PatelThis study analyses the use of machine learning for predicting the academic performance of students using their academic information from the institution, combined with socio-economic information that comes from outside sources. The collection of information is done using structured questionnaires as well as through data extraction from the Student Information System (SIS). To increase the reliability of models built, a … …Journal of Computer Science, Vol. 22, Issue 5 · 26 May 2026 · 1,419 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCapital Structure and Corporate Performance in Nigeria Petroleum Industry: Panel Data AnalysisDare Funso David, Sola OlorunfemiProblem statement: The actual impact of capital structure on corporate performance in Nigeria has been a major problem among researchers that has not been resolved. Approach: The study looks at the impact of capital structure on corporate performance in the Nigerian Petroleum Industry. Results: The study employed panel data analysis by using Fixed-effect estimation, Random-effect estimation and Maximum likelihood estimation. … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 10,336 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePredictive Modeling Applied to Structured Clinical Data Extracted from Electronic Health Records: An Architectural Hypothesis and A First ExperimentAlessandra Pieroni, Alessandro Cabroni, Francesca Fallucchi, Noemi ScarpatoPredictive analysis is one of current important issues in the healthcare context. A lot of patients’ input data can be obtained from their Electronic Health Records. In our research, we propose a general architecture named Health Prediction Architecture. Initially, we consider that data refer to strongly structured health datasets (no free text). Our objectives are related to exploring some problems … …Journal of Computer Science, Vol. 17, Issue 9 · 7 Sep 2021 · 6,571 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Numerical Computation of Rational Structures and Asymptotic Standard Deviations in Causal Time Series DataConcepción González-Concepción, María Candelaria Gil-Fariña, Celina Pestano-GabinoProblem statement: The specific properties of data series are of primary importance in several sciences. In the field of time series analysis, several researchers have considered the rational approximation theory, particularly the Padé Approximation and Orthogonal Polynomials. Approach: In this study, an approach for the statistical significance of two numerical methods, the r-s and q-d algorithm, was proposed which made … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,049 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQuaternary Tree Structure as a Novel Method for Huffman Coding TreeAhsan Habib, Mohammed Jahirul Islam, Mohammad Shahidur RahmanThe binary code used by the current Huffman-based techniques slows down decoding speed. The quaternary Huffman coding method is a fresh take on the traditional Huffman coding that is suggested in this study. Each symbol is encoded into a quaternary code rather than a binary code using the quaternary Huffman coding technique. For Huffman coding, a quaternary code stream necessitates … …Journal of Computer Science, Vol. 19, Issue 9 · 24 Aug 2023 · 5,419 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of the Prospects for Developing Storage and Processing Complexes for Multiformat Media DataVladimir Zhanovich Kuklin, Islam Alexandrovich Alexandrov, Alexander Alexandrovich Umyskov, Abas Khasanovich LampezhevA distinctive feature of multifunctional systems for supporting multimedia services on a single platform is the heterogeneity of incoming streams and requests, which requires optimization of resource use under physical constraints. In this regard, it is relevant to develop promising proposals for the functional structure and technical characteristics of complexes for storing and processing multi-format media data, which was the … …Journal of Computer Science, Vol. 18, Issue 12 · 6 Dec 2022 · 5,577 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFully Retroactive Priority Queues using Persistent Binary Search TreesJoseWagner de Andrade Junior, Rodrigo Duarte SeabraClassic dynamic data structures maintains itself subject to sequence S of operations and answer queries using the latest version of the data structure. Retroactive data structures are those which allow making a modification or a query in any version of this data structure through its timeline. These data structures are used in some geometric problems and in problems related with … …Journal of Computer Science, Vol. 16, Issue 7 · 14 Jul 2020 · 7,006 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Test on the Multivariate Behrens–Fisher Problem in High–Dimensional Data by Block Covariance EstimationParanut Sukcharoen, Samruam ChongcharoenIn this paper, we proposed a new testing statistic for testing the equality of mean vectors from two multivariate normal populations when the covariance matrices are unknown and unequal in high–dimensional data. A new test is proposed based on the idea of keeping more information from the sample covariance matrices as much as possible. A proposed test is invariant under … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 2 Apr 2019 · 7,369 accessesView PDFCite
