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). ...
A Novel Condition to the Harmonic of the Velocity Vector Field of a Curve In R-N
(Hindawi Ltd, 2017)
In this paper, a condition is obtained for the harmonic of the velocity vector field in the curve family passing through the fixed p and q points in Rn It shows that the condition can be expressed in terms of the curvature ...
A Generalization of J - Quasipolar Rings
(Univ Miskolc Inst Math, 2017)
In this paper we introduce a class of quasipolar rings which is a generalization of J-quasipolar rings. Let R be a ring with identity. An element a is an element of R is called delta-quasipolar if there exists p(2) = p is ...
Modules Which Are Self-P-Injective Relative To Projection Invariant Submodules
(Ovidius Univ Press, 2017)
In this article, we focus on modules M such that every homomorphism from a projection invariant submodule of M to M can be lifted to M. Although such modules share some of the properties of PI-extending (i.e., every ...
Odd Burr Lindley Distribution With Properties And Applications
(Hacettepe Univ, Fac Sci, 2017)
In this study, we introduce a new model called the Odd Burr Lindley distribution which extends the Lindley distribution and has increasing, bathtub and upside down shapes for the hazard rate function. It includes the odd ...
On 3-Uniform Hypergraphs Without A Cycle Of A Given Length
(Elsevier Science Bv, 2017)
We study the maximum number of hyperedges in a 3-uniform hypergraph on n vertices that does not contain a Berge cycle of a given length l. In particular we prove that the upper bound for C2k+1-free hypergraphs is of the ...
A New Improved Estimator of Population Mean in Partial Additive Randomized Response Models
(Hacettepe Univ, Fac Sci, 2017)
In this study, we have developed a new improved estimator for the population mean estimation of the sensitive study variable in Partial Additive Randomized Response Models (RRMs) using two non-sensitive auxiliary variables. ...
Autocorrelation Corrected Standard Error For Two Sample T-Test Under Serial Dependence
(Hacettepe Univ, Fac Sci, 2017)
The classical two-sample t-test assumes that observations are independent. A violation of this assumption could lead to inaccurate results and incorrectly analyzing data leads to erroneous statistical inferences. However, ...
Hartley-Ross Type Unbiased Estimators Using The Stratified Random Sampling
(Hacettepe Univ, Fac Sci, 2017)
This study mentions Hartley-Ross type unbiased ratio estimators of the finite population mean in the stratified random sampling using the auxiliary variable. We propose the unbiased estimators using the estimators in Kadilar ...
The Exponentiated Kumaraswamy-Power Function Distribution
(Hacettepe Univ, Fac Sci, 2017)
In this paper, the exponentiated Kumaraswamy-power function distribution is introduced. Some structural properties of the proposed distribution including the shapes of the density, hazard and quantile functions are explored. ...
