The distribution of the Liu-type estimator of the biasing parameter in elliptically contoured models
Arashi, M.; Nadarajah, Saralees; Akdeniz, Fikri (Taylor & Francıs ınc, 2017)We derive the density function of the stochastic shrinkage parameters of the Liu-type estimator in elliptical models. The correctness of derivation is checked by simulations. A real data application is also provided. -
Efficiency of the generalized difference-based liu estimators in semiparametric regression models with correlated errors
Akdeniz, Fikri; Duran, Esra Akdeniz; Roozbeh, Mahdi; Arashi, Mohammad (TAYLOR & FRANCIS LTD, 2015)In this paper, a generalized difference-based estimator is introduced for the vector parameter beta in the semiparametric regression model when the errors are correlated. A generalized difference-based Liu estimator is ... -
Efficiency of the generalized-difference-based weighted mixed almost unbiased two-parameter estimator in partially linear model
Akdeniz, Fikri; Roozbeh, Mahdi (TAYLOR & FRANCIS INC, 2017)In this paper, a generalized difference-based estimator is introduced for the vector parameter in partially linear model when the errors are correlated. A generalized-difference-based almost unbiased two-parameter estimator ... -
Generalized difference-based weighted mixed almost unbiased liu estimator in semiparametric regression models
In classical linear regression analysis problems, the ordinary leastsquares (OLS) estimation is the popular method to obtain the regression weights, given the essential assumptions are satisfied. However, often, in real-life ... -
Generalized difference-based weighted mixed almost unbiased ridge estimator in partially linear models
Akdeniz, Fikri; Roozbeh, Mehdi (Springer New York LLC, 2017)In this paper, a generalized difference-based estimator is introduced for the vector parameter (Formula presented.) in partially linear model when the errors are correlated. A generalized difference-based almost unbiased ... -
Generalized difference-based weighted mixed almost unbiased ridge estimator in partially linear models
Akdeniz, Fikri; Roozbeh, Mahdi (2019)In this paper, a generalized difference-based estimator is introduced for the vector parameter β in partially linear model when the errors are correlated. A generalized difference-based almost unbiased ridge estimator is ... -
Matematik öğretmenlerinde mesleki tükenmişliği etkileyen bazı demografik özelliklerin incelenmesi: Adana ili örneği
Elbadi, Bilal Can (Çağ Üniversitesi Sosyal Bilimler Enstitüsü, 2019)Tükenmişlik sendromu, 21.yy çalışma hayatına negatif yönde tesir eden öğelerden bir tanesidir. Bilindiği üzere eğitim kurumları işlevsel ve yapısal açıdan oldukça kompleks teşkilatlardır. Freudenberger ilk defa 1974 yılında ... -
A new difference-based weighted mixed Liu estimator in partially linear models
Akdeniz, Esra; Akdeniz, Fikri; Roozbeh, Mahdi (TAYLOR & FRANCIS LTD, 2018)In this paper, a generalized difference-based estimator is introduced for the vector parameter beta in the partially linear model when the errors are correlated. A generalized difference-based Liu estimator is defined for ... -
Restricted estimator in two seemingly unrelated regression model
Erdugan, Funda; Akdeniz, Fikri (unıv punjab, 2016)This article is concerned with the estimation problem of multicollinearity in two seemingly unrelated regression (SUR) equations with linear restrictions. We propose a restricted feasible SUR estimates of the regression ... -
Revıvıng some geometrıc aspects of shrınkage estımatıon ın lınear models
Akdeniz, Fikri; Özturk, Fikri (ANKARA UNIV, FAC SCI, 2019)It is well known that the least squares estimator is the best linear unbiased estimator of the parameter vector in a classical linear model. But, it is 'too long' as a vector and unreliable, confidence intervals are broad ... -
Üniversite öğrencilerinde matematik kaygı ve tutumlarının incelenmesi: Çağ Üniversitesi örneklemi
Demiroğulları, Burcu (Çağ Üniversitesi Sosyal Bilimler Enstitüsü, 2018)Ülkemizde insanların matematik dersine karşı yarattığı kaygı ve tutum yıllardır tartışılan bir konudur. Bu konu ile ilgili bir çok çalışmaya rastlamaktayız. Bu araştırmanın amacı; yükseköğretim düzeyinde öğrenim gören ...
