Comparison of the results of factorial experiments, fractional factorial experiments, regression trees and MARS for fuel consumption data
(2010)In this study effects that are significant on the fuel consumption of F-4 aircrafts are analyzed by using different statistical methods and the results of those different methods are compared. The response variable of every ... -
A comparison of various tests of normality
(Taylor & Francis LTD, 2007)This article studies twelve different normality tests that are used for assessing the assumption that a sample was drawn from a normally distributed population and compares their powers. The tests in question are chi-square, ... -
A comparison study of forecasting financial fuzzy time series by artificial neural networks
(Vilnius Gediminas Technical University, 2010)Forecasting financial time series is an important area for various investors and business practices. Fuzzy time series models which have been successfully applied to handle nonlinear problems have become popular in recent ... -
Comparison study of P-spline and univariate additive model (CUBIC smoothing spline) in time-series prediction
(Vilnius Gediminas Technical University, 2010)Smoothing splines used in many nonparametric problems to make a good approximation for smoothed functions in recent years. It is discussed two nonparametric techniques called P-spline and univariate additive model (cubic ... -
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 ... -

Comparisons of the Turkish, English, German, French, Russian and Spanish languages for communications of same semantic content
(2006)The language itself may be regarded as a code for certain conceptual entities. From this point of view, in this study comparisons of the Turkish, English, German, French, Russian and Spanish languages considered as alternate ... -
Conditional entropy distribution of Istanbul stock market value
(Routledge Journals, Taylor & Francis LTD, 2010)In this study, the conditional distributions of Istanbul stock market value are obtained by using entropy optimization. The aim is to observe how the fluctuation of the conditional distributions changes according to different ... -

Dellphi programming of normality tests
(World Scientific And Engineering Acad And Soc, 2008)In this study, the source codes for the formulations of various normality tests are established on Delphi programming language. The main advantage of the programs given on this paper is that one can easily perform the ... -
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 ... -
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 ... -

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 ... -
Determining the problems of disabled employees: a survey study conducted in Eskisehir, Turkey
(Routledge Journals, Taylor & Francis LTD, 2011)In this study, disabled people, employed using a policy based quota method, were asked about their working lives by means of a survey. In order to do this, the population was defined as disabled people working for companies ... -
A development of entropy optimization methods
(2006)In this study by considering entropy optimization measure on the given set of moment vector functions special functional according to each measure is defined. Via the moment vector functions giving the least and the greatest ... -
Development of fuzzy ((X) over bar) over tilde - (R) over tilde and ((X) over bar) over tilde - (S) over tilde control charts using alpha-cuts
(Elsevier Science Inc, 2009)Statistical process control (SPC) is an approach that uses statistical techniques to monitor the process. Shewhart introduced the control charts that are one of the most important techniques of quality control to detect ... -
Different estimation methods for the parameters of the extended Burr XII distribution
(Taylor & Francis LTD, 2013)The extended three-parameter Burr XII (EBXII) distribution has recently attracted considerable attention for modeling data from various scientific fields since it yields a wide range of skewness and kurtosis values. However, ... -
The distribution of minimizing maximum entropy: Alternative to Weibull distribution for wind speed
(2006)In the present study, we have constructed MinMaxEnt distribution alternative to the Weibull distribution for the wind speed. MinMaxEnt distribution minimizes the special maximum entropy functional in the concrete set of ... -
Distributions of Wind Speed at Different Heights
(IEEE, 2016)In this study, the parameters of different distributions such as the Weibull, Rayleigh, Lognormal, Gamma and Generalized Gamma, which are used for modelling wind speed, at the different heights 10 and 30 m, have been ...
