A Comparison Study of Performance Measures and Length of Intervals in Fuzzy Time Series by Neural Networks
(World Scientific Publ Co Pte LTD, 2009)
Deciding length of intervals and choosing performance measures have important issues to forecast fuzzy time series. Many forecasting studies accept MSE(Mean squared error) for performance measure and use only one kind of ...
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 ...
Derivation of ME estimator of a mixture of two normal distributions
(World Scientific And Engineering Acad And Soc, 2008)
In this study, we obtain the parameters of a mixture density by using the principle of maximum equality which is based on Shannon's entropy measure. Since this procedure doesn't require constructing the likelihood function ...
Estimation Method Based on MinMaxEnt Distribution for Missing Value in Time Series
(World Scientific Publ Co Pte LTD, 2009)
In this study, MinMaxEnt distribution out of Generalized Entropy Optimization Distributions with moment functions and moment values dependent on parameter are introduced. MaxEnt distribution for observed time series is ...
The individuals control charts for burr distributed and Weibull distributed data
(2006)
Constructing the control limits supposes the assumption of the normality. However, there are numerous studies on the control charts when the underlying distribution is non-normal. Several authors have investigated the ...
Portfolio optimization with entropy measure
(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 ...
Estimating the location and scale parameters of the Weibull distribution: An application from engineering
(Acta Press Anaheim, 2007)
There exist various methods for estimating the location and scale parameters of the Weibull distribution. The maximum likelihood estimators (MLE), moment estimators (ME), generalized spacing estimators (GSE), modified ...
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 ...
Temel İstatistik Eğitiminde R For Wındows Paket Programı Kullanımı
(2005)
Türkiye’de 20 Üniversitede İstatistik eğitim programı bulunmaktadır. Öğrenciler eğitimin ilk yılında istatistiğin temel kavram ve teoremlerini öğrenmektedir. Bu temel kavram ve teoremlerin daha anlaşılır ve görsel algılamaya ...
Türkiye'de illere göre iç göç hareketlerinin modern kümeleme teknikleri ile incelenmesi
(2007)
Türkiye’de özellikle büyük sehirlere dogru bir göç yasanmaktadır. Fakat son yıllarda büyüksehir belediyeleri, köylerine ya da kasabalarına geri dönmek isteyenlere çesitli kolaylıklar saglamaktadır. Bu çalısmada iç göç ...
