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 ... -
A comparative study of hybrid, neural networks and nonparametric regression models in time series prediction
(2009)This paper presents a comparative study of the hybrid models, neural networks and nonparametric regression models in time series forecasting. The components of these hybrid models are consisting of the nonparametric ... -
Reliability and validity of Turkish version of the impact on family scale: Assessment of depressive symptoms and quality of life in mothers with cerebral palsied children
(2009)The pragmatic aims of this study were to investigate the reliability and validity of the Turkish version of the Impact on Family Scale (IFS) and to evaluate the impact of having disabled children on mothers. Two hundred ... -
An application of fuzzy time series to improve ISE forecasting
(2010)The problem of fuzzy time series forecasting plays an important role in many scientific areas such as statistics and neural networks. While forecasting fuzzy time series, most of forecasting applications use the same length ... -
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 ... -
ANN forecasting models for ISE national-100 index
(Wayne State University, 2010)Prediction of the outputs of real world systems with accuracy and high speed is crucial in financial analysis due to its effects on worldwide economics. Because the inputs of the financial systems are timevarying functions, ... -

Signs of change in Turkey's working class: workers' age-related perceptions in the modern manufacturing sector
(Routledge Taylor & Francis LTD, 2003)This paper explores the possible effects of the increasing exposure to modernity on younger workers in some sectors of developing countries with special reference to those employed in advanced manufacturing in Turkey. In ... -
Simulation for the complex Bingham distribution
(Kluwer Academic Publ, 2004)The complex Bingham distribution is relevant for the shape analysis of landmark data in two dimensions. In this paper it is shown that the problem of simulating from this distribution reduces to simulation from a truncated ... -
Comparison of ARIMA, neural networks and hybrid models in time series: tourist arrival forecasting
(Taylor & Francis LTD, 2007)For time series forecasting, different artificial neural network (ANN) and hybrid models are recommended as alternatives to commonly used autoregressive integrated moving average (ARIMA) models. Recently, combined models ... -
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, ... -
Generalized entropy optimization problems and the existence of their solutions
(Elsevier Science BV, 2007)In the present study we have formulated a generalization of entropy optimization problems (GEOP), proposed sufficient conditions for the existence of solution. We have suggested also a new method based on a priori evaluations ... -
Fuzzy Regression Control Chart Based on α-cut Approximation
(Atlantis Press, 2010)The fuzzy regression control chart is a functional technique to evaluate the process in which the average has a trend and the data represents a linguistic or approximate value. In this study, the theoretical structure of ... -
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 ... -
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, ... -
Comparison of goodness-of-fit measures in probit regression model
(Taylor & Francis Inc, 2007)This article examines several goodness-of-fit measures in the binary probit regression model. Existing pseudo-R-2 measures are reviewed, two modified and one new pseudo-R-2 measure are proposed. For the probit regression ... -
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 ... -
Estimation of Censored Regression Model in the Case of Non-Normal Error
(Yildiz Technical University, 2018)For the censored regression model, it is well-known that while classical least squares estimation yields biased and nonconsistent estimator, maximum likelihood estimator (MLE) is consistent and efficient. Tobit estimator ... -
Analysis of international debt problem using artificial neural networks and statistical methods
(Springer, 2010)It is known from the scientific researches that artificial neural networks are alternatives of statistical methods such as regression analysis and classification in recent years. Since multi-layer backpropagation neural ... -
Asymmetric control limits for small samples
(Springer, 2009)When designing control charts, it is usually assumed that the measurement in the subgroups are normally distributed. The assumption of normality implies that the control limits for a chart for sample averages will be ...
