Kedi Sürüsü Optimizasyonuna Dayalı Yeni Bir Bulanık Zaman Serisi Yaklaşımı
(Fen Bilimleri Enstitüsü, 2018)Since there are no theoretical constraints such as the model assumption and the number of observations, the importance of the preferred fuzzy time series instead of classical time series is day by day increasing in analysis ... -
Genelleştirilmiş Doğrusal Mekânsal Modellere Koşullu Otoregresif Model Yaklaşımı
(Fen Bilimleri Enstitüsü, 2018)Spatial analysis is a method used to describe spatial patterns on a geographical region. During this analysis, the attributes and location information of the objects forming the spatial data are used. Response variable ... -
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, ... -
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 ... -
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 ... -
THE IMPORTANCE OF FAT-TAILED AND SKEWED DISTRIBUTIONS IN MODELING VALUE-AT-RISK
(Fen Bilimleri Enstitüsü, 2018)Most of the Value-at-Risk models assume that financial returns are normally distributed, despite the fact that they are commonly known to be left skewed, fat-tailed and excess kurtosis. Forecasting Value-at-Risk with ... -
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, ... -

(Fen Bilimleri Enstitüsü, 2018)In today’ s conditions, increasing the need for such as assessing, analyzing and making forward estimates of data, has increased the demand for data mining methods. In this study, classification and regression estimating ... -
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 ... -
Yaşam Çözümlemesinde Kümelenmiş Başarısızlık Süresi
(Fen Bilimleri Enstitüsü, 2018)Survival analysis is a collection of statistical methods for analyzing data where the outcome variable is the time until the occurrence of an event of interest. The time is called "failure time" or "survival time". Here, ... -
Tramo/Seats Yöntemi İle İmalat Sanayi Üretim Endeksinin Modellenmesi: Doğrudan Ve Dolaylı Yaklaşımların Karşılaştırılması
(Fen Bilimleri Enstitüsü, 2018)Time series show that seasonal movements repeated from year to year. These seasonal movements conceal the characteristics of the economic time series and prevent to make reliable analysis. For this reason, economic time ... -
Uyarlanabilir Küme Örneklemesinde Oransal Tahminler
(Fen Bilimleri Enstitüsü, 2018)In this study, simple and ratio estimators of Horvitz-Thompson and Hansen-Hurwitz are investigated in the literature in order to obtain an estimate of population mean in adaptive cluster sampling. These estimators do not ... -
