Research ArticleOpen accessQuadratic Discriminant Analysis of Dengue Viruses Disease Incidence in PalembangYulia Resti, Noriszura Ismail, Marieska VerawatyPalembang is classified as a city that has tropical climate with abundant rainfall, even in the driest month. These characteristics indicate that the city has a high potential for the occurrence of dengue virus disease. The areas of incidence of dengue virus disease in Palembang can be classified into five areas; South, Center, North, West and East. The aim of … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 30 May 2017 · 7,478 accessesView PDF Cite

Research ArticleOpen accessESTIMATION OF CLAIM COST DATA USING ZERO ADJUSTED GAMMA AND INVERSE GAUSSIAN REGRESSION MODELSYulia Resti, Noriszura Ismail, Saiful Hafizah JamaanIn actuarial and insurance literatures, several researchers suggested generalized linear regression models (GLM) for modeling claim costs as a function of risk factors. The modeling of claim costs involving both zero and positive claims experience has been carried out by fitting the claim costs collectively using Tweedie model. However, the probability of zero claims in Tweedie model is not allowed … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 11 Jul 2013 · 7,263 accessesView PDF Cite

Research ArticleOpen accessHandling the Dependence of Claim Severities with Copula ModelsYulia Resti, Noriszura Ismail, Saiful Hafizah JaamanProblem statement: Several studies have been carried out on the modeling of claim severity data in actuarial literature as well as in insurance practice. Since it is well established that the claim cost distributions generally have positive support and are positively skewed, the regression models of Gamma and Lognormal have been used by practitioners for modeling claim severities. However, the … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,528 accessesView PDF Cite
