Comparison of Parametric and Non-Parametric Estimation Methods in Linear Regression Model
Zaman, Tolga; Alakuş, Kamil (2019)In this study, the aim was to review the methods of parametric and non-parametric analyses in simple linear regression model.The least squares estimator (LSE) in parametric analysis of the model, and Mood-Brown and Theil-Sen ... -
Comparison of Resampling Methods in Multiple Linear Regression
Zaman, Tolga; Alakus, Kamil (Editura Bibliotheca-Bibliotheca Publ House, 2019)In order to estimate model parameters in multiple regression models, resampling methods of bootstrap and jackknife are used. Resampling methods are used as an alternative readjustment method to the least squares method ... -

An improved class of robust ratio estimators by using the minimum covariance determinant estimation
Bulut, Hasan; Zaman, Tolga (Taylor & Francis Inc, 9999)In this article, ratio estimators for the population mean have suggested using the robust covariance estimation under the simple random scheme. Zaman and Bulut have developed a class of ratio-type estimators for the mean ... -
Improvement in Estimating the Population Mean in Simple Random Sampling Using Information on Two Auxiliary Attributes and Numerical Application in Agricultural Engineering
Zaman, Tolga; Toksoy, Erdem (Parlar Scientific Publications (P S P), 2019)This study proposes a family of estimators for calculating population mean using auxiliary attributes based on an adaption of the estimators presented by Abu-Dayyeh et al. [1]. Theoretically, we obtain the mean square error ... -
Modified ratio estimators using robust regression methods
Zaman, Tolga; Bulut, Hasan (Taylor & Francis Inc, 2019)When there is an outlier in the data set, the efficiency of traditional methods decreases. In order to solve this problem, Kadilar etal. (2007) adapted Huber-M method which is only one of robust regression methods to ... -
Modified regression estimators using robust regression methods and covariance matrices in stratified random sampling
Zaman, Tolga; Bulut, Hasan (Taylor & Francis Inc, 2020)This article proposes new regression-type estimators by considering Tukey-M, Hampel M, Huber MM, LTS, LMS and LAD robust methods and MCD and MVE robust covariance matrices in stratified sampling. Theoretically, we obtain ... -
Robust Hedonik Modellerin Karşılaştırılması: Beetle Türkiye Piyasa Fiyatını Etkileyen Faktörlerin İncelenmesi
Bulut, Hasan; Zaman, Tolga (2018)Bu çalışmanın amacı Türkiye’de “Vosvos” ya da “Kaplumbağa” olarak da adlandırılan Beetle araçların fiyatını etkileyen faktörleri belirlemektir. Beetle özellikle ikinci el piyasasında son model araçlardan daha pahalı ... -
The Simulation and Minimization of Loss Probability in the Tandem Queueing with Two Heterogeneous Channels
Zobu, Mujgan; Saglam, Vedat; Sagir, Murat; Yucesoy, Erdinc; Zaman, Tolga (Hindawi Ltd, 2013)A stochastic model consisting of two heterogeneous channels and having no waiting room in front of each is considered. A customer who has completed his service in channel 1 while channel 2 is busy blocks channel 1 with ... -
Some Robust Estimation Methods and Their Applications
Zaman, Tolga; Alakuş, Kamil (2015)Bu çalışmada doğrusal regresyon modellerinin tahmininde yaygın olarak kullanılan EKK tekniğinin varsayımlarının sağlanmamasından kaynaklanan problemlerin çözümü için kullanılan Robust regresyon yöntemleri incelenmiştir. ... -
