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 ... -
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 human height from infancy through adulthood at different levels of parental education
(NATURE RESEARCH, 2020)Genetic factors explain a major proportion of human height variation, but differences in mean stature have also been found between socio-economic categories suggesting a possible effect of environment. By utilizing a ... -

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 ... -
A new wrapped exponential distribution
(Springer Heidelberg, 2018)We introduce a new wrapped exponential distribution named transmuted wrapped exponential (TWE) distribution, for the modeling of circular datasets by using the Transmutation Rank-Map method. This method is employed for the ... -
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) ... -
On Using Structural Patterns In Data For Classification
(PUSHPA PUBLISHING HOUSE, 2020)There are some interesting approaches for classification such as semi-supervised algorithms, algorithms that learn distance functions, and various extensions and generalizations of support vector machines. In this study, ... -
Parameter estimation of some Kumaraswamy-G type distributions
(Springer Heidelberg, 2017)Since Kum-G distributions have additional two parameters, the estimation of parameters becomes an interesting problem by itself. In this study, we consider parameter estimation of Kum-Weibull, Kum-Pareto and Kum-Power ... -
Parental Education and Genetics of BMI from Infancy to Old Age: A Pooled Analysis of 29 Twin Cohorts
(Wiley, 2019)Objective The objective of this study was to analyze how parental education modifies the genetic and environmental variances of BMI from infancy to old age in three geographic-cultural regions. Methods A pooled sample of ... -
Performance and stochastic stability of the adaptive fading extended Kalman filter with the matrix forgetting factor

Properties and Inference for a New Class of Generalized Rayleigh Distributions with an Application
(Sciendo, 2019)In the present paper, we introduce a new form of generalized Rayleigh distribution called the Alpha Power generalized Rayleigh (APGR) distribution by following the idea of extension of the distribution families with the ... -
Properties and inference for a new class of XGamma distributions with an application
