On the distribution of a boundary functional of semi-Markovian random walk process with reflecting and delaying barriers
(2001)Bu çalışmada sıfır seviyesinde yansıtan ve \beta(\beta0) seviyesinde tutan bariyerli yarı-Markov rasgele yürüyüş süreci inşa edilmiştir. Ayrıca \gamma sürecin ilk kez yansıma anı olmak üzere, sürecin bir sınır fonksiyoneli ... -
Determination of dependency parameter in joint distribution of dependent risks by fuzzy approach
(Elsevier Science Bv, 2006)Frechet bounds for distribution of sum of dependent risks and Farlie-Gumbel-Morgenstein (FOM) distribution family are suggested for the analysis of dependent risks. Behaviour of the coefficient of dependency in FGM ... -
Neural networks approach for determining total claim amounts in insurance
(Elsevier Science Bv, 2009)In this study, we present an approach based on neural networks, as an alternative to the ordinary least squares method, to describe the relation between the dependent and independent variables. It has been suggested to ... -
Risk factors for smoking behavior among university students
(2011)Amaç: Sigara içme, Türkiye’de yaygın bir alışkanlık ve dünyada önemli bir halk sağlığı sorunudur. Bu çalışmada, anket formu kullanarak Kırıkkale Üniversitesi öğrencilerinin sigara içme riskinin artışı ile bağlı olan ... -
A note on the characterization of pareto distribution by the hazard rate of upper record values
(Isoss Publ, 2013)Let {X-i, i = 1 2, ... } be a sequence of independent and identically distributed (iid) random variables with absolutely continuous (with respect to Lebesgue measure) cumulative distribution function (cdf) F(x) with F(1) ... -

Self-inserted foreign body and attention-deficit/hyperactivity disorder: Evaluated by the Conners' Parent Rating Scales-Revised
(Elsevier Ireland Ltd, 2013)Objectives: We aimed to evaluate the relationship between attention-deficit/hyperactivity disorder (ADHD) and self-inserted foreign bodies (SIFBs) in children by the Conners' Parent Rating Scales-Revised (CPRS-R). Methods: ... -
Bivariate Pseudo-Gompertz distribution and concomitants of its order statistics
(Elsevier Science Bv, 2013)This paper presents a new bivariate Pseudo-Gompertz distribution that sprouts from the classical Gompertz distribution and possesses the features of pseudo-distribution functions. In addition to some standard properties ... -
Computational results on the compound binomial risk model with nonhomogeneous claim occurrences
(Elsevier Science Bv, 2014)The aim of this paper is to give a recursive formula for non-ruin (survival) probability when the claim occurrences are nonhomogeneous in the compound binomial risk model. We give recursive formulas for non-ruin (survival) ... -
Risk Factors Influencing Smoking Behavior: A Turkish Twin Study
(Cambridge Univ Press, 2014)Aim: In this study, we introduce the first twin study in Turkey, focusing on smoking behavior, and laying the foundation to register all twins born in Turkey for research purposes. Using Turkish twins will contribute to ... -
The CODATwins Project: The Cohort Description of Collaborative Project of Development of Anthropometrical Measures in Twins to Study Macro-Environmental Variation in Genetic and Environmental Effects on Anthropometric Traits
(Cambridge Univ Press, 2015)For over 100 years, the genetics of human anthropometric traits has attracted scientific interest. In particular, height and body mass index (BMI, calculated as kg/m(2)) have been under intensive genetic research. However, ... -
Using of fractional factorial design (rk-p) in data envelopment analysis to selection of outputs and inputs
(Hacettepe Univ, Fac Sci, 2015)Data envelopment analysis (DEA) is a linear programming based technique for measuring the relative performance of organisational units where the presence of multiple inputs and outputs makes comparisons difficult. We used, ... -
Kontenjans tablolarının analizinde log-lineer modellerin kullanımı ve sigara bağımlılığı üzerine bir uygulama
(2015)İki yönlü kontenjans tabloların istatistiksel analizlerinde ki-kare analizi kullanılmakta ancak daha büyük boyutlu kontenjans tabloların analizinde yetersiz kalmaktadır. Üç veya daha çok boyutlu ... -
Zygosity Differences in Height and Body Mass Index of Twins From Infancy to Old Age: A Study of the CODATwins Project
(Cambridge Univ Press, 2015)A trend toward greater body size in dizygotic (DZ) than in monozygotic (MZ) twins has been suggested by some but not all studies, and this difference may also vary by age. We analyzed zygosity differences in mean values ... -
Generalized Bertrand curves with timelike (1,3)-normal plane in Minkowski space-time
(Academic Publication Council, 2015)In this paper, we reconsider the (1,3)-Bertrand curves with respect to the casual characters of (1,3)-normal plane which is a plane spanned by the principal normal and the second binormal vector fields of the given curve. ... -
Genetic and environmental influences on height from infancy to early adulthood: An individual-based pooled analysis of 45 twin cohorts
(Nature Publishing Group, 2016)Height variation is known to be determined by both genetic and environmental factors, but a systematic description of how their influences differ by sex, age and global regions is lacking. We conducted an individual-based ... -
Genetic and environmental influences on adult human height across birth cohorts from 1886 to 1994
(Elife Sciences Publications Ltd, 2016)Human height variation is determined by genetic and environmental factors, but it remains unclear whether their influences differ across birth-year cohorts. We conducted an individual-based pooled analysis of 40 twin cohorts ... -
Bacterial adhesion to braided surgical sutures: an in vitro study
