Research ArticleOpen accessAll words, across the recordA COMPARATIVE STUDY OF ANTI-PHOSPHATIDYL INOSITOLE ANTIBODIES IN PATIENTS WITH MYOCARDIAL INFARCTION AND HEALTHY SUBJECTSAbdolreza Sotoodeh Jahromi, Mohammad Shojaei, Fatemeh Mehdizadeh et al.Immune system and inflamation is widely known to play a key role in the development and progression of cardiovascular diseases. Anti-Phospholipid (aPL) antibodies may act in the induction of immunological response leading to the development of Acute Myocardial Infarction (AMI). Anti-Phosphatidyl Inositole (PI) Antibody (Ab) has been seen in various diseases including rheumatoid arthritis, systemic lupus erythematosus and anti-phospholipid antibody … …American Journal of Immunology, Vol. 10, Issue 1 · 23 Jan 2014 · 7,185 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Comparative Study in Classification Techniques for Unsupervised Record Linkage ModelMohammadreza Ektefa, Fatimah Sidi, Hamidah Ibrahim et al.Problem statement: Record linkage is a technique which is used to detect and match duplicate records which are generated in data integration process. A variety of record linkage algorithms with different steps have been developed in order to detect such duplicate records. To find out whether two records are duplicate or not, supervised and unsupervised classification techniques are utilized in … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 8,199 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordMachine Learning-Based Detection of Credit Card Fraud: A Comparative StudyZainab Khamees Alkhateeb, Abeer Tariq MaoloodOne of the fastest-growing problems with a high impact on the financial sector is financial fraud. Recently, data mining has been identified as one of the effective ways of detecting fraudulent credit card transactions. As a data mining problem, the detection of fraudulent credit card transaction is a challenging task due to the following reasons: (i) The frequent changes in … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 25 Dec 2019 · 7,780 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparative Analysis of the Artificial Neural Networks Options Pricing Model Under Constant and Time-Variant VolatilitiesHanningtone Meshack Simiyu, Anthony Gichuhi Waititu, Jane Aduda AkinyiOption pricing using artificial neural networks (ANN) model while relaxing the assumption of constant volatility still remains a challenge. The conventional practice for pure ANN models has been to either model volatility using the very ANN model and have the model output fed as an input to the ANN option pricing model, or to make allowances for a large number … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 20 Jul 2019 · 7,010 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Comparative Study on the Information Effect of Stock Lending and Borrowing and Short Selling between the Korea Stock Exchange and the New Stock ExchangeYeongsuk Cho, Youngsik KwakThe purpose of this study is to compare the information effect of Stock Lending and Borrowing (SLB) and short selling between the Korea Stock Exchange (KRX) and the New York Stock Exchange (NYSE). While most previous studies analyzed the information effect with a focus on short selling, this study links short selling to SLB and examines how SLB and short … …American Journal of Economics and Business Administration, Vol. 10, Issue 1 · 4 Oct 2018 · 8,174 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordApplication of a Multi Stage Method to Assess the Landscape Alteration Induced by Quarrying Sites: A Comparative AnalysisDario Lippiello, Guido Alfaro Degan, Marco De Agostini, Mario PinzariThe aim of this study is to provide a design tool to forecast the effects that extraction methods and reclamation plans will generate on the land surrounding quarry sites. The method is based on a graphical approach and it consists of three consecutive phases. The first phase focuses on the quarry plant and aims to quantify the extent of the … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 2 Sep 2016 · 6,960 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA COMPARATIVE STUDY OF COMBINED FEATURE SELECTION METHODS FOR ARABIC TEXT CLASSIFICATIONAisha Adel, Nazlia Omar, Adel Al-ShabiText classification is a very important task due to the huge amount of electronic documents. One of the problems of text classification is the high dimensionality of feature space. Researchers proposed many algorithms to select related features from text. These algorithms have been studied extensively for English text, while studies for Arabic are still limited. This study introduces an investigation … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,433 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordA Comparative Study of the Performances of the OLS and some GLS Estimators when Stochastic Regressors are both Collinear and Correlated with Error TermsKayode AyindeThe Classical Linear Regression Model assumes that regressors are non – stochastic, independent and uncorrelated with the error terms. These assumptions are not always tenable especially where regressors are not often assumed fixed in repeated sampling. In this paper, with stochastic regressors, the performances of the Ordinary Least Square (OLS) and some Generalized Least Square (GLS) estimators are investigated and … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,343 accessesView PDFCite
