The smoothing parameter selection problem in smoothing spline regression for different data sets
(2007)This paper studies smoothing parameter selection problem in nonparametric regression based on smoothing spline method for different data sets. For this aim, a Monte Carlo simulation study was performed. This simulation ... -
A semiparametric additive regression model: Investigation of house price in Eskisehir (Turkey)
(2007)In this paper, different regression models are obtained to examine relation between house price and house features in Centrum of Eskisehir Province (Turkey). The statistical analyses of this paper indicate that some of ... -
Generalized entropy optimization distributions dependent on parameter in time series
(2010)In this paper, we have proposed Generalized Entropy Optimization Problems (GEOP) concerned with parameters which consist of maximizing Entropy Functional subject to constraints dependent on parameters. Therefore, MinMaxEnt ... -
Comparison of spline approximation with the modified likelihoods in the presence of nuisance parameter
(2010)The likelihood functions from independent studies can be easily combined, and the combined likelihood function serves as a meaningful indication of the support the observed data give to the various parameter values. This ... -
Comparison of artificial neural networks and ridge regression for two different economic problems
(2005)The least squares estimators of the regression coefficients are the best linear unbiased estimators. That is, of all possible estimators that are both linear functions of the data and unbiased for the parameters being ... -
Design of Fuzzy (u)over-tilde Control Charts
(Old City Publishing Inc, 2011)When expressing any data in linguistic terms related to a quality characteristic, traditional statistical techniques are insufficient to capture the vagueness in the data. Linguistic data can be transformed into numerical ... -
Interval Type-2 Fuzzy Analytic Network Process for Modelling a Third-party Logistics (3PL) Company
(Old City Publishing Inc, 2017)The Fuzzy Analytic Network Process (ANP) is generally used for solving multi-criteria decision making (MCDM) problems by considering the pairwise comparison between criteria/sub-criteria, and inner/outer dependencies among ... -
An Estimation Method of Membership Function for Given Fuzzy Data
(Yildiz Technical University, 2017)In the present study for given fuzzy data an estimation method based on Max(F)Ent measure and generalized entropy optimization methods is suggested. A set of successive values of estimated membership function is defined ... -
Time Series Forecasting Using a Hybrid Neural Networks and Nonparametric Regression Model
(Isoss Publ, 2014)The focus in this paper embraces the hybrid models whose components are nonparametric regression and artificial neural networks. Smoothing spline, regression spline and additive regression models are considered as the ... -
Estimation of Clearness Index Model Via Crs, Tprs and Mars
(Isoss Publ, 2011)Nonparametric approach is more flexible than parametric approach in assuming that f belongs to a smooth family of functions. Hence, a nonparametric approach does not require an assumption of linearity. Based on our motivating ... -
An Application of Fuzzy Coding in Multiple Correspondence Analysis for Transforming Data from Continuous to Categorical
(Old City Publishing Inc, 2012)In some research, it can be necessary to know the categorical data groups to which the data measured by interval and ratio scale belong. The fuzzy sets principle can be used to transform the original continuous data into ... -
ROBUST 2(k) FACTORIAL DESIGNS: NON-NORMAL SYMMETRIC DISTRIBUTIONS
(Isoss Publ, 2012)Senoglu (2005, 2007a) considered the estimation and hypothesis testing procedures for the 2(k) factorial designs when the error distributions are skew. They obtained the modified maximum likelihood (MML) estimators of the ... -
Robust Estimation With the Skew T(2) Distribution
(Isoss Publ, 2013)In this paper, a skew extension of the Student's t distribution with two degrees of freedom is used to model data sets that have skewness and heavy-tails. Its parameters are estimated using two different approaches based ... -
Determination of the criteria preferred in entering private pension system by Analytical Hierarchy Process
(2012)Bireysel emeklilik şirketleri sistemlerine daha çok müşteri kazandırmak için önemli çalışmalarda bulunmaktadırlar. Bu önemli çalışmalardan biri de tüketicilerin diğer şirketlere olan tercih sebeplerini ortaya çıkarmak ve ... -
Performance of Shannon’s Maximum Entropy Distribution Under Some Restrictions: an Application on Turkey’s Annual Temperatures
(2015)İstatistik biliminde entropi oldukça önemli bir yere sahiptir. Son yıllardaki çalışmalarda entropinin neredeyse bilimin her dalında yer aldığı görülebilir. İnformasyon teorisinde, Entropi, rassal bir değişkenin belirsizliğinin ... -
Öğrenci başarı notları için robust faktör analizi uygulaması
(2006)Faktör analizi, yaygın kullanılan çok değişkenli bir analiz tekniğidir. Faktör analizinin temelinde varyans-kovaryans matrisi ve korelasyon matrisi hesaplanması aşaması bulunmaktadır. Asal bileşenler analizi, faktör analizi ... -
Farklı Olasılık Yoğunluk Fonksiyonları Kullanarak Rüzgar Gücü Potansiyelinin Tahmini
(2016)Sürekli rassal değişken olarak kabul edilen rüzgâr hızı istatistiksel dağılımlarla karakterize edilir ve ortalama rüzgâr gücü tahminleri yapılır. Weibull dağılımı rüzgar enerjisi alanında kabul edilmiş dağılımdır. Ancak ... -
Gördes yöresi klinoptilolitin (Doğal ve modifiye)su buharı adsorpsiyonu
(2007)Bu çalışmada Gördes klinoptiloliti (klinoptilolitçe zengin doğal tüf örneği) (CLN) ve bundan itibaren hazırlanan katyonik formlar (Li-, Na-, K-, Mg-, Ca-, ZH1- ve ZH2-CLN örnekleri), üzerinde zamana bağlı olarak, 30?C, ... -
A Comparison of Germany, Holland and Turkey Football Leagues with Cramér-Von Mises Test
(2016)Football, which is assumed to be played with more than 250 million players in more than 200 countries all around the world, is a sports activity that appeals to the masses. In this respect, football, apart from the sports ... -
A New Method of Approximation For Fuzzy Membership Function with Application
(2017)In the present study we have formulated a new Maximum Fuzzy Entropy Problem (Max(F)EntP) for fuzzy membership function and proposed sufficient conditions for existence of its solution. Mentioned problem consists of ...
