Bağımsız Bileşenler Analizi ile Çoklu Bağlantı Sorununa Bir Yaklaşım
(Fen Bilimleri Enstitüsü, 2019-07-19)In the first part of the thesis, although it is a multivariate statistical method, Independent Components Analysis which is mostly used in the engineering field, which is not known much in statistics, has been discussed ... -
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. ... -
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 ... -

Bilgi Içeren Durdurma Varlığında Yinelemeli Olay Süreci
(Fen Bilimleri Enstitüsü, 2013)Informative censoring is an important issue which have to be taken into account while modelling recurrent event data. Informative censoring might happen as a result of terminal event such as death or drop out of individuals ... -
Boylamsal ve Yaşam Verilerinin Parametrik Bileşik Modellemesi
(Fen Bilimleri Enstitüsü, 2019)Longitudinal data consist of repeated measurements obtained from the same units at certain time intervals, while survival data consists of time until the occurrence of any event under consideration. There are different ... -
Budanmış Ortalamalar için Karşılaştırma Testleri
(Fen Bilimleri Enstitüsü, 2021)Statistical significance tests, such as Student’s t test, ANOVA-F test, are widely used in many disciplines, including medicine, psychology, and biology. For these tests to exact control over the rate of a Type I error, ... -
Bulanık Regresyon Analizinde Monte Carlo Yöntemi ve Uzman Sistemler
(Fen Bilimleri Enstitüsü, 2015)In this study, the use of fuzzy expert system in Monte Carlo method, which is used for estimating fuzzy linear regression model parameters, is proposed for determining the parameter intervals for the first time.For this ... -
Comparison Of Efficacy Between Low-Fluence And Half-Dose Verteporfin Photodynamic Therapy For Chronic Central Serous Chorioretinopathy
(2014)Purpose To compare the efficacy of low-fluence photodynamic therapy (PDT) and PDT with half-dose verteporfin in chronic central serous chorioretinopathy (CSC). Patients and methods The medical records of 64 eyes from 60 ... -
Çeşitli Tabakalı Sıralı Küme Örneklemesi Tasarımlarında Kitle Ortalamasının Tahmin Edilmesi
(Fen Bilimleri Enstitüsü, 2017-06-02)Ranked Set Sampling is used when taking exact measurement of sampling units is difficult but ranking is easy. Stratified sampling is a sampling method when the population is heterogeneous. In this thesis, the classical, ... -
Değişen Katsayılı Regresyon Modeli İle Gebelerin Ortalama Arteriyel Kan Basıncına Etki Eden Risk Faktörlerinin Belirlenmesi
(Fen Bilimleri Enstitüsü, 2018-09-25)Varying Coefficient Models are used to reveal properties of multidimensional data among nonparametric regression models. Since these models allow the coefficients to change over the variable called the "index variable", ... -
Deneysel Dağılım Fonksiyonuna Dayalı Yeni Uyum İyiliği Testleri
(Fen Bilimleri Enstitüsü, 2018)Distributional assumptions are at the core of statistical methods. Goodness-of-fit test statistics are used to examine whether there is a difference between the sample distribution and the empirical distribution. Although ... -
