#### The Effect Of Changing Scores For Multi-Way Tables With Open-Ended Ordered Categories

(Hacettepe Univ, Fac Sci, 2016)

Log-linear models are used to analyze the contingency tables. If the variables are ordinal or interval, because the score values affect both the model significance and parameter estimates, selection of score values has ...

#### Some Imputation Methods For Missing Data In Sample Surveys

(Hacettepe Univ, Fac Sci, 2016)

The present work suggests some imputation methods to deal with the problems of non-response in sample surveys. The imputation methods presented in this work lead to the precise estimation strategies of population mean. ...

#### Modified Welch Test Statistic For Anova Under Weibull Distribution

(Hacettepe Univ, Fac Sci, 2016)

A modification to Welch test statistic is proposed to test the equality of population means of various groups under a Weibull distribution. The proposed test statistic is simple and corresponds to the standard Welch test ...

#### Further Results On Fibre Products Of Kummer Covers And Curves With Many Points Over Finite Fields

(Amer Inst Mathematical Sciences-Aims, 2016)

We study fibre products of an arbitrary number of Kummer covers of the projective line over F-q under suitable weak assumptions. If q - 1 = r(n) for some prime r, then we completely determine the number of rational points ...

#### 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.

#### The Generalized Reciprocal Super Catalan Matrix

(Scientific Technical Research Council Turkey-Tubitak, 2016)

The reciprocal super Catalan matrix studied by Prodinger is further generalized, introducing two additional parameters. Explicit formulae are derived for the LU-decomposition and their inverses, as well as the Cholesky ...

#### Nearly Perfect Sequences With Arbitrary Out-Of-Phase Autocorrelation

(Amer Inst Mathematical Sciences-Aims, 2016)

A sequence of period n is called a nearly perfect sequence of type gamma if all out-of-phase autocorrelation coefficients are a constant gamma. In this paper we study nearly perfect sequences (NPS) via their connection to ...

#### 1-Dimensional Harnack Estimates

(Amer Inst Mathematical Sciences-Aims, 2016)

Let u be a non-negative super-solution to a 1-dimensional singular parabolic equation of p-Laplacian type (1 < p < 2). If u is bounded below on a time-segment {y} x (0, T] by a positive number M, then it has a power like ...

#### Structural Stability Analysis Of Solutions To The Initial Boundary Value Problem For A Nonlinear Strongly Damped Wave Equation

(Scientific Technical Research Council Turkey-Tubitak, 2016)

In this paper the initial-boundary value problem for a nonlinear strongly damped wave equation is considered. We analyze the structural stability of solutions of the nonlinear strongly damped wave equation with coefficients ...

#### Evaluation Of Spectrum Of 2-Periodic Tridiagonal-Sylvester Matrix

(Scientific Technical Research Council Turkey-Tubitak, 2016)

The Sylvester matrix was first defined by JJ Sylvester. Some authors have studied the relationships between certain orthogonal polynomials and the determinant of the Sylvester matrix. Chu studied a generalization of the ...
