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 ... -
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: ... -
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 ... -
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 ... -
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, ... -
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. ... -
Assessment of Third Molar Impaction Pattern and Associated Clinical Symptoms in a Central Anatolian Turkish Population
(Karger, 2016)Objectives: The purpose of this study was to assess the pattern of third molar impaction and associated symptoms in a Central Anatolian Turkish population. Material and Methods: A total of 2,133 impacted third molar teeth ... -
Characterizations of Geometric and Discrete Pareto Distributions Based on the Conditional Distribution of kth Records
(Atlantis Press, 2016)The poblem of characterizing of discrete probability distributions is an important problem. Recently many new results are obtained in characterization of distributions using kth records. Based on the distributional properties ... -
Performance and stochastic stability of the adaptive fading extended Kalman filter with the matrix forgetting factor
(Sciendo, 2016)In this paper, the stability of the adaptive fading extended Kalman filter with the matrix forgetting factor when applied to the state estimation problem with noise terms in the non-linear discrete-time stochastic systems ... -
Genetic and environmental effects on body mass index from infancy to the onset of adulthood: an individual-based pooled analysis of 45 twin cohorts participating in the COllaborative project of Development of Anthropometrical measures in Twins (CODATwins) study
(Oxford Univ Press, 2016)Background: Both genetic and environmental factors are known to affect body mass index (BMI), but detailed understanding of how their effects differ during childhood and adolescence is lacking. Objectives: We analyzed the ... -
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 ... -
