An empirical likelihood approach for complex sampling
No full textSurvey data are often collected with unequal probabilities from a stratified population. We propose an empirical likelihood approach for sample data selected with unequal probabilities. We show that the empirical likelihood ratio statistic follows a chi-squared distribution asymptotically. The approach proposed does not rely on variance estimates, re-sampling or joint-inclusion probabilities, even when the parameter of interest is not linear. Standard confidence intervals based on variance estimates may give poor coverages, when normality does not hold. This can be the case with skewed data and outlying values. This paper contains the main results of Oguz-Alper & Berger (2016a,c) published by Oxford University Press. Oguz-Alper & Berger’s (2016a) empirical likelihood confidence interval has good coverages, even when the sampling distribution of the point estimator is not normal
2D modeling temperature development of mass concrete structures at early age - 2018
No full textAlper Yıkıcı (MEF Author)In this paper, a 2D finite volume analysis methodology was used to predict temperature development within three different bridge pier caps. MATLAB® was employed to generate a program that solves the governing heat transfer equation where development of thermo-physical concrete properties was defined as a function of degree of hydration. The rate of heat generation was obtained experimentally via adiabatic calorimetry and the activation energy was determined following the ASTM C 1074 procedure to implement equivalent age concept. 2D finite volume analysis results were presented in comparison with the recorded concrete temperatures from the field. Accordingly, temperature time histories at the center and the side surface of the bridge pier caps were predicted reasonably well using the concrete mixture information and the measured concrete hydration properties.WOS:0005502533000742-s2.0-85134814600Conference Proceedings Citation Index- ScienceProceedings PaperHaziranYÖK - 2017-1

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Pricing of Sovereign Credit Risk: Evidence from Advanced Economies During the Financial Crisis
No full textWe investigate the pricing of sovereign credit risk over the period 2008-10 for selected advanced economies by examining two widely-used indicators: sovereign credit default swap (CDS) and relative asset swap (RAS) spreads. Cointegration analysis suggests the existence of an imperfect market arbitrage relationship between the cash (RAS) and the derivatives (CDS) markets, with price discovery taking place in the latter. Likewise, panel regressions aimed at uncovering the fundamental drivers of the two indicators show that the CDS market, although less liquid, has provided a better signal for sovereign credit risk during the period of the recent financial crisis. © 2013 John Wiley & Sons Ltd
