Sensitivity To Imputation Models And Assumptions In Receiver Operating Characteristic Analysis With Incomplete Data
(Taylor & Francis Ltd, 2015)
Modern statistical methods using incomplete data have been increasingly applied in a wide variety of substantive problems. Similarly, receiver operating characteristic (ROC) analysis, a method used in evaluating diagnostic ...
Assessing Proportionality Assumption In The Adjacent Category Logistic Regression Model
(Int Press Boston, Inc, 2014)
Ordinal logistic regression models are classified as either proportional odds models, continuation ratio models or adjacent category models. The common model assumption of these models is that the log odds do not depend ...
Oscillation Of P(X)-Laplacian Elliptic Inequalities With Mixed Variable Exponents
(Element, 2013)
Oscillation criteria are established for p(x)-Laplacian elliptic inequalities with mixed variable nonlinearities of the form u[del.(A(x)vertical bar del u vertical bar(p(x)-2) del u) + < b(x), vertical bar del u vertical ...
Q-Counting Hypercubes in Lucas Cubes
(Scientific Technical Research Council Turkey-Tubitak, 2018)
Lucas and Fibonacci cubes are special subgraphs of the binary hypercubes that have been proposed as models of interconnection networks. Since these families are closely related to hypercubes, it is natural to consider the ...
Using A Multidimensional Irt Framework To Better Understand Differential Item Functioning (Dif): A Tale Of Three Dif Detection Procedures
(Sage Publications Inc, 2017)
The theoretical reason for the presence of differential item functioning (DIF) is that data are multidimensional and two groups of examinees differ in their underlying ability distribution for the secondary dimension(s). ...
Quadratic Forms of Codimension 2 Over Finite Fields Containing F-4 and Artin-Schreier Type Curves
(Academic Press Inc Elsevier Science, 2012)
Let F-q be a finite field containing F-4. Let k >= 2 be an integer. We give a full classification of quadratic forms over F-q(k) of codimension 2 provided that certain three coefficients are from F-4. As an application of ...
Hedef Programlama ve En Küçük Kar Farkı Yaklaşımları ile Optimal Reasürans
(Fen Bilimleri Enstitüsü, 2019)
The aim of this study is to contribute to the optimal reinsurance studies, which have a considerable role in the actuarial literature, by considering the situation from a perspective that takes into account the insurer and ...
Assessment of Landslide Susceptibility By Decision Trees in the Metropolitan Area of Istanbul, Turkey
(Hindawi Ltd, 2010)
The main purpose of the present study is to investigate the possible application of decision tree in landslide susceptibility assessment. The study area having a surface area of 174.8 km(2) locates at the northern coast ...
Probabilistic Risk Assessment in Medium Scale for Rainfall-Induced Earthflows: Catakli Catchment Area (Cayeli, Rize, Turkey)
(Hindawi Publishing Corporation, 2011)
The aim of the present study is to introduce a probabilistic approach to determine the components of the risk evaluation for rainfall-induced earthflows in medium scale. The Catakli catchment area (Cayeli, Rize, Turkey) ...
Algoritmik Biyomimikri Yöntemi ile Dijital Tasarım
(Güzel Sanatlar Enstitüsü, 2019-06-28)
At the beginning of the 21st century, with the Fourth Industrial Revolution: Industry 4.0 a new age has begun and a new life model is taking shape. The digital atmosphere covers the physical atmosphere and appears as the ...
Time Scale In Least Square Method
(Hindawi Publishing Corporation, 2014)
Study of dynamic equations in time scale is a new area in mathematics. Time scale tries to build a bridge between real numbers and integers. Two derivatives in time scale have been introduced and called as delta and nabla ...
Anti-Ramsey Number of Matchings in Hypergraphs
(Elsevier Science Bv, 2013)
A k-matching in a hypergraph is a set of k edges such that no two of these edges intersect. The anti-Ramsey number of a k-matching in a complete s-uniform hypergraph H on n vertices, denoted by ar(n, s, k), is the smallest ...
Dicompleteness And Real Dicompactness Of Ditopological Texture Spaces
(Elsevier Science Bv, 2011)
The authors consider interrelations between the completeness of certain initial diuniformities and the real dicompactness of completely biregular bi-T-2 nearly plain ditopological spaces. Completions and real dicompactifications ...
Di-Extremities And Totally Bounded Di-Uniformities
(Univ Nis, Fac Sci Math, 2018)
In our previous studies, we have defined a counterpart, called a di-extremity, to the classical notion proximity in the complement-free setting of a texture. In this article, we will investigate relationship between totally ...
Continuous Dependence Of Solutions To Fourth-Order Nonlinear Wave Equation
(Hacettepe Univ, Fac Sci, 2016)
This paper gives a priori estimates and continuous dependence of the solutions to fourth-order nonlinear wave equation.
A Coanalytic Menger Group That Is Not Sigma-Compact
(Scientific Technical Research Council Turkey-Tubitak, 2018)
Under V = L we construct coanalytic topological subgroups of reals, demonstrating that even for definable groups of reals, selection principles may differ.
A Generalization Of Rickart Modules
(Belgian Mathematical Soc Triomphe, 2014)
Let R be an arbitrary ring with identity and M a right R-module with S = End(R) (M). In this paper we introduce pi-Rickart modules as a generalization of Rickart modules. pi-Rickart modules are also a dual notion of dual ...
Legendrian Torus Knots in Lens Spaces
(Scientific Technical Research Council Turkey-Tubitak, 2018)
In this study, we first classify all topological torus knots lying on the Heegaard torus in lens spaces, and then we study Legendrian representatives of these knots. We classify oriented positive Legendrian torus knots in ...
Joint Prior Distributions for Variance Parameters in Bayesian Analysis of Normal Hierarchical Models
(Elsevier Inc, 2015)
In random effect models, error variance (stage 1 variance) and scalar random effect variance components (stage 2 variances) are a priori modeled independently. Considering the intrinsic link between the stages 1 and 2 ...
