Basit Rastgele Örnekleme Yönteminde Kitle Varyans Tahmin Edicilerinin Kitle Ortalamasının Güven Aralıklarında Kullanılması
(Fen Bilimleri Enstitüsü, 2018-07)In this study, some variance estimators in simple random sampling method have been investigated. These estimators have been proposed to use in the estimation of confidence intervals of the population mean in this study. ... -
Basit rastgele örneklemede cevapsızlık durumunda kitle ortalaması için tahmin edici önerileri
(Fen Bilimleri Enstitüsü, 2022)There is an approach in which information about various variables in the estimators used for the estimation of unknown population parameters is fully obtained and there is no missing information. Despite this approach in ... -
BASİT VE TABAKALI RASTGELE ÖRNEKLEMEDE ÜSTEL FONKSİYONU KULLANAN KİTLE ORTALAMASI TAHMİN EDİCİLERİ
(Fen Bilimleri Enstitüsü, 2017-06-14)In this study, we investigated estimators with exponential functions for estimation of mean estimator in simple and stratified random samplings. Family of estimators based on the exponential function is proposed for both ... -
Bayesci grafik modelleri
(Fen Bilimleri Enstitüsü, 2001)Posterior distributions obtained by Bayesian approach usually have high dimensions when the models are rather complicated. Therefore, to reach the marjinal distributions from the models is analitically intractable. The aim ... -
Bayesian Estimation of Order-Restricted and Unrestricted Association Models
(Elsevier Inc, 2013)Association models include score parameters to multiplicatively represent the hierarchy between the levels of the considered ordinal factor. If order restrictions are placed on the scores, an estimation problem becomes a ... -
