Misusage of statistics in medical research
(2007)The inappropriate use of statistical method and technique cause time and cost losts and it can be misleading to other scientific researhes. So in this study the main statistical error sources in medical research are discussed ... -
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 ... -
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 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 ... -
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 ... -
C programming on waiting line systems
(World Scientific And Engineering Acad And Soc, 2008)In this article, the particular queue will be a place where customers are waiting for service behind each other. For the purpose of this study, a simulation in C language is created in order to simulate the aforementioned ... -
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 ... -
