Markov Zinciri Monte Carlo Yönteminin Dinamik Doğrusal Modellere Uygulanması
(Fen Bilimleri Enstitüsü, 2013)This study deals with implementing three different types of dynamic linear models using dlm package in R. These models are the steady model, the linear growth model and the combined model as a second order polynomial model ... -
Medyan Sıralı Küme Örneklemesi Yönteminde Kitle Ortalamasının Tahmini
(Fen Bilimleri Enstitüsü, 2018-10-08)Ranked set sampling methods are used when it is costly or difficult to measure the sampling units precisely with respect to the variable of interest and also when these units can be more easily ranked with respect to the ... -
Mekânsal Panel Veri Modelleri: Havacılık Sektöründe Bir Uygulama
(Fen Bilimleri Enstitüsü, 2021-01-25)When analyzing the data with geographical units (cities, countries, states, regions, etc.), it should be investigated whether neighboring units have spatial effects on each other. Because it is assumed that geographical ... -
Meteorolojik Mekansal Verilerin İstatistiksel Yöntemler ile Analizi: Çatalan Baraj Gölü Havzası Örneği
(Fen Bilimleri Enstitüsü, 2019)In hydrology, which is a sub-discipline of earth sciences, spatial analysis methods are needed to determine the spatial arial distribution (x, y, z, t) of the hydrometeorological data as point (x, t) time series data. ... -
Nedensellik Analizi ve Gri İlişkisel Analiz İle Performans Sıralaması: G20 Ülkeleri Üzerine Bir Çalışma
(Fen Bilimleri Enstitüsü, 2018-11)In this thesis study, it is aimed to measure and rank the economic performances of countries by using the basic economic parameters specified in the study by using Gray Relational Analysis (GRA) method, which is one of the ... -
Ölçüm Hatalı Açıklayıcı Değişkenli Cox Regresyon Modeline Bayesci Yaklaşım
(Fen Bilimleri Enstitüsü, 2020)The Cox regression model with the measurement error covariate can cause an important bias when estimating coefficients by maximizing the known partial likelihood function. In this case, alternative estimation methods have ... -
Ölçüm Sistemleri Analizinde Varyans Bileşenlerinin Tahminleri
(Fen Bilimleri Enstitüsü, 2018)In this thesis study, using the ANOVA, Maximum Likelihood Estimation (ML), Restricted Maximum Likelihood Estimation (REML) and Minimum Norm Quadratic Estimation (MINQUE) methods, how to apply these estimates to the Measurement ... -
Örnekleme Kuramında Yüzdelik Tahmin Edicileri
(Fen Bilimleri Enstitüsü, 2018)Economic variables can have extreme values and in this case, these extreme values have a very strong impact on the mean. In such cases, using median and quantiles is more convenient instead of using mean. In literature, ... -
ÖRNEKLEME YÖNTEMLERİNDE HARTLEY-ROSS TAHMİN EDİCİSİNE DAYALI YENİ TAHMİN EDİCİLER
(Fen Bilimleri Enstitüsü, 2017-04-03)In this thesis, we have used Hartley-Ross Method to obtain unbiased estimators. We have proposed the families of estimators based on Hartley-Ross estimators in both Simple Random Sampling and Stratified Random Sampling. ... -
Portföy Optimizasyonunda Değiştirilmiş Parçacık Sürü Optimizasyonu Yaklaşımı
(Fen Bilimleri Enstitüsü, 2014)One of the most studied problem in optimization world is portfolio selection problem which is based on knapsack problems. Portfolio optimization is a NP-hard problem. Because of that heuristic methods are preferred solving ... -
Rastgeleleştirilmiş Yanıt Modellerinde Oran ve Ortalama Tahmin Edicileri
(Fen Bilimleri Enstitüsü, 2013)Randomized Response Models(RRM) are used to reduce nonrespondents rates andbiased responses arising from surveys on sensitive subjects such as gambling,alcoholism, sexual abuse, drug addiction, abortion, tax evasion, illegal ... -
REGRESSION DISCONTINUITY DESIGN: AN APPLICATION IN ECONOMICS
(Fen Bilimleri Enstitüsü, 2017)Regression Discontinuity Design (RDD) is developed as an alternative to ex-post facto experiments. It is an approach causally estimating treatment effects in non-experimental designs. The Regression Discontinuity Methodology ... -
Regresyon Süreksizliği Yönteminde Parametrik Olmayan Tahmin
(Fen Bilimleri Enstitüsü, 2018)Regression discontinuity is a quasi-experimental impact evaluation method of assessment which is used in cases where control and effect groups can not be generated before the implementation of the program. In this method, ... -
Risk Analizinde Bulanık Mantığın Kullanılmasına Yönelik Bir Uygulama Çalışması
(Fen Bilimleri Enstitüsü, 2018)In order to be able to produce solutions to the problems we face in our daily lives, researchers are trying to transfer the focused processes to analysis systems as realistically as possible. The success of implementation ... -
Sağlam Kısmi En Küçük Kareler Regresyonu
(Fen Bilimleri Enstitüsü, 2014)Partial Least Squares Regression (PLSR) method is a Latent Variables (LVs) regression method. Therefore, in this method, firstly, a set of unrelated LVs is predicted and then, the relationship of these LVs with dependent ... -
Sayma Verisi İçin Regresyon Modelleri Ve Bir Uygulama
(Fen Bilimleri Enstitüsü, 2018)Regression analysis is used to measure the relationship between a dependent variable and one or more explanatory variables. When the dependent variables consist of discrete non-negative values, the use of counting data ... -
Sonradan Tabakalamalı Örnekleme Yönteminde Rastgeleleştirilmiş Cevap Modelleri
