Fuzzy regression control chart
Şentürk, Sevil (World Scientific Publ Co Pte LTD, 2008)The fuzzy set theory is a powerful method to analyze the statistical data which includes ambiguity or vague comes from the structure of the process, measurement systems or environmental conditions. Crisp value collected ... -
Hybrid Models Combining Neural Networks and Nonparametric Regression Models Used for Time Series Prediction
Aydın, Dursun; Mammadov, Mammadagha (World Scientific And Engineering Acad And Soc, 2009)In this paper, we proposed the hybrid models whose components are nonparametric regression and artificial neural networks. Smoothing spline, regression spline and additive regression models are considered as the nonparametric ... -
Investigation of house price in Eskisehir (Turkey) by using semiparametric additive regression model
Omay, Rabia Ece; Aydın, D. (World Scientific and Engineering Academy and Society, 2006)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 ... -
A new concept of relative suitability of moment function sets
Shamilov, Aladdin; Giriftinoğlu, Çiğdem; Usta, İlhan; Mert Kantar, Yeliz (Elsevier Science Inc, 2008)In modeling statistical data by using entropy optimization distributions, the choice of a suitable moment function set and various combinations of their elements are very important. It is also important to have criteria ... -
On developed estimation methods via unique and multiple parametrization
Giriftinoğlu, C.; Shamılov, Aladdin (2012)In the present study, two methods, based on entropy optimization principle, to estimate missing (or forecasting) values in the given time series are suggested. In the first method successively replaces the missing values ... -
Optimum smoothing parameter selection for penalized least squares in form of linear mixed effect models
Aydın, Dursun; Mammadov, Mammadagha (Taylor & Francis LTD, 2012)In this article, we discuss the penalized least squares problem which has many advantageous computational properties. This method based on penalized spline (P-spline) smoothing can be formulated to fit into a linear mixed ... -
Portfolio optimization with entropy measure
Usta, İlhan; Mert Kantar, Yeliz (Acta Press Anaheim, 2007)In portfolio management, the selection of portfolio weights has received considerable interest. Considering the expected return, risk and uncertainty, the portfolio distribution is to be determined. The maximum entropy ... -
A simulation study with different number of observation using nonparametric regression splines
Memmedli, Memmedaga; Nizamitdinov, A. (2011)In this study we made a simulation study using various nonparametric techniques. The methods that we have used in this study are following: regression spline, penalized spline, and their Bayesian versions: adaptive Bayesian ... -
Spatial Analysis of Unemployment Rate with Literacy Rate and Socioeconomic Development Index for cities of Turkey
Mert Kantar, Yeliz; Günay Aktaş, Semra (Int Business Information Management Assoc-Ibima, 2015)The objective of the study is to investigate the spatial pattern of unemployment rate with socio economic development index (SDI) and literacy rate for 81 cities of Turkey and also the spatial correlation between these ... -
