The Relationship Between Parental Defense Intensity and Nest Site Characteristics in Eurasian Magpie (Pica Pica L.) - an Assessment With the Classification Methods
(Corvinus University Budapest, 2017)Nest defense behavior varies among species and depends on different factors. However little is known of the influence of urbanization and nest characteristics on the nest defense intensity as parental investment of the ... -
Reliability and validity of Turkish version of the impact on family scale: Assessment of depressive symptoms and quality of life in mothers with cerebral palsied children
(2009)The pragmatic aims of this study were to investigate the reliability and validity of the Turkish version of the Impact on Family Scale (IFS) and to evaluate the impact of having disabled children on mothers. Two hundred ... -
Ridge-Type MML Estimator in the Linear Regression Model
(Springer International Publishing Ag, 2019)Ridge regression is widely used to deal with the multicollinearity problem. However, traditional ridge estimator (Hoerl and Kennard 1970) loses its efficiency in the presence of outliers, since it is obtained based on least ... -
ROBUST 2(k) FACTORIAL DESIGNS: NON-NORMAL SYMMETRIC DISTRIBUTIONS
(Isoss Publ, 2012)Senoglu (2005, 2007a) considered the estimation and hypothesis testing procedures for the 2(k) factorial designs when the error distributions are skew. They obtained the modified maximum likelihood (MML) estimators of the ... -
Robust 2k factorial designs: Non-normal symmetric distributions
(2012)Şenoglu (2005, 2007a) considered the estimation and hypothesis testing procedures for the 2k factorial designs when the error distributions are skew. They obtained the modified maximum likelihood (MML) estimators of the ... -
Robust Estimation for Parameters of the Extended Burr Type III Distribution
(Taylor & Francis Inc, 2015)We consider various robust estimators for the extended Burr Type III (EBIII) distribution for complete data with outliers. The considered robust estimators are M-estimators, least absolute deviations, Theil, Siegel's ... -
Robust Estimation With the Skew T(2) Distribution
(Isoss Publ, 2013)In this paper, a skew extension of the Student's t distribution with two degrees of freedom is used to model data sets that have skewness and heavy-tails. Its parameters are estimated using two different approaches based ... -
Robust estimation with the skew t2 distribution
(2013)In this paper, a skew extension of the Student's t distribution with two degrees of freedom is used to model data sets that have skewness and heavy-tails. Its parameters are estimated using two different approaches based ... -
Robust factorial ANCOVA with LTS error distributions
(Hacettepe University, Fac Sci, 2018)In this study, parameter estimation and hypotheses testing in the balanced factorial analysis of covariance (ANCOVA) model, when the distribution of error terms is long-tailed symmetric (LTS) are considered. The unknown ... -
Robust ridge and robust Liu estimator for regression based on the LTS estimator
(Taylor & Francis LTD, 2013)In the multiple linear regression analysis, the ridge regression estimator and the Liu estimator are often used to address multicollinearity. Besides multicollinearity, outliers are also a problem in the multiple linear ... -
The role of the government in enhancing sustainable entrepreneurships
(Inderscience Enterprises Ltd., 2019)The goal of this paper is to point out the role of government in fostering the framework for sustainable entrepreneurship, with special emphasis on the public policy instruments supporting this scope and provide evidence ... -
Sampling frame coverage and domain adjustment procedures for internet surveys
(Springer, 2013)The objective of this paper is to define and compare alternative sampling frames for the representative population coverage as a basis for sample selection in internet surveys. The study aims to provide a methodology for ... -
A semiparametric additive regression model: Investigation of house price in Eskisehir (Turkey)
(2007)In this paper, different regression models are obtained to examine relation between house price and house features in Centrum of Eskisehir Province (Turkey). The statistical analyses of this paper indicate that some of ... -

Signs of change in Turkey's working class: workers' age-related perceptions in the modern manufacturing sector
(Routledge Taylor & Francis LTD, 2003)This paper explores the possible effects of the increasing exposure to modernity on younger workers in some sectors of developing countries with special reference to those employed in advanced manufacturing in Turkey. In ... -
Simulation for the complex Bingham distribution
(Kluwer Academic Publ, 2004)The complex Bingham distribution is relevant for the shape analysis of landmark data in two dimensions. In this paper it is shown that the problem of simulating from this distribution reduces to simulation from a truncated ... -
A simulation study on generalized pareto mixture model
(Springer Verlag, 2015)The Generalized Pareto Distribution is commonly used for extreme value problems. Especially, the values which exceed the finite threshold, is the focus in extreme value problems like in insurance sector. The Generalized ... -
