    In this study, pf and df of single order statistic of nonidentical discrete random variables are obtained. These functions are also expressed in integral form. Finally, pf and df of extreme of order statistics of random ...
  • Bulut, Y.; Gungor, M.; Yuzbasi, B.; Ozbey, F.; Canpolat, E. (Eudoxus press, llc, 1424 beaver traıl drıve, cordova, tn 38016 usa, 2016)
    In this study, the joint distributions of order statistics of innid discrete random variables are expressed in the form of an integral. Then, the results related to pf and df are given.
  • Aydin, D.; Yüzbaşi, B.; Ahmed, S.E. (American Scientific Publishers, 2016)
    In this article, we introduce a modified ridge type estimator for the vector of parameters in a partially linear model. This estimator is a generalization of the well-known Speckman's approach and is based on smoothing ...
  • Ahmed, S. Ejaz; Yuzbasi, Bahadir (Taylor & francıs ltd, 2-4 park square, mılton park, abıngdon or14 4rn, oxon, england, 2016)
    We present efficient estimation and prediction strategies for the classical multiple regression model when the dimensions of the parameters are larger than the number of observations. These strategies are motivated by ...
  • Güngör, Mehmet; Bulut, Y. (Eudoxus Press, LLC, 2017)
    In this study, joint probability density and distribution functions of any d order statistics of innid continuous random vectors are expressed. Then, some results connecting distributions of order statistics of innid random ...
  • Yuzbasi, Bahadir; Ahmed, S. Ejaz; Gungor, Mehmet (Inst nacıonal estatıstıca-ıne, av antonıo jose almeıda, 2, lısbon, 1000-043, portugal, 2017)
    We suggest pretest and shrinkage ridge estimation strategies for linear regression models. We investigate the asymptotic properties of suggested estimators. Further, a Monte Carlo simulation study is conducted to assess ...
  • Ahmed, Syed Ejaz; Yuzbasi, Bahadir (Sprınger ınternatıonal publıshıng ag, gewerbestrasse 11, cham, ch-6330, swıtzerland, 2017)
    We consider an efficient prediction in sparse high dimensional data. In high dimensional data settings where d >> n, many penalized regularization strategies are suggested for simultaneous variable selection and estimation. ...
  • Hassan, M. Kabir; Kayhan, Selim; Bayat, Tayfur (Elsevıer bilim bv, po kutusu 211, 1000 ae amsterdam, hollanda, 2017)
    We examine possible links between CDS spreads and the value of the Turkish lira against the U.S. dollar by using the recently developed rolling window causality method as well as the Markov Switching Vector Autoregressive ...
  • Yüzbaşı, Bahadır; Sik, M. Şamil; Demiralp, Ahmet (VINCA INST NUCLEAR SCI, MIHAJLA PETROVICA-ALASA 12-14 VINCA, 11037 BELGRADE. POB 522, BELGRADE, 11001, SERBIA, 2018)
    An important issue is that the respiratory mortality may be a result of air pollution which can be measured by the following variables: temperature, relative humidity, carbon monoxide, sulfur dioxide, nitrogen dioxide, ...
  • Güngör, Mehmet (ACADEMIC PUBLICATION COUNCIL, PO BOX 17225, KHALDIYA 72453, KUWAIT, 2018)
    In this study, the joint distributions of order statistics from innid variables from a truncated distribution is expressed in terms of the specialized identities. Then, some results connecting distributions of order ...
  • Yuzbasi, Bahadir; Ahmed, S. Ejaz; Asar, Yasin (Ieee, 345 e 47th st, new york, ny 10017 usa, 2018)
    In this study, we propose a new method called L1 norm correlation based estimation in quantile regression in high-dimensional sparse models where the number of explanatory variables is large, may be larger than the number ...
  • Sirkeci, I.; Zeren, F. (Transnational Press London Ltd, 2018)
    In this article, we discuss the role of diaspora as a business network and an opportunity window for foreign market entry according to the concept of diaspora market entry or transnational market entry mode. As sources of ...
