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 ...
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 ...
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 ...
Examining cronbach alpha, theta, omega reliability coefficients according to the sample size
(Wayne State University, 2007)
Differentiations according to the sample size of different reliability coefficients are examined. It is concluded that the estimates obtained by Cronbach alpha and teta coefficients are not related with the sample size, ...
Estimation of clearness index model via CRS, TPRS and mars
(2011)
Nonparametric approach is more flexible than parametric approach in assuming that f belongs to a smooth family of functions. Hence, a nonparametric approach does not require an assumption of linearity. Based on our motivating ...
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 ...
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 ...
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 ...
Modified generalized p-value and confidence interval by Fisher's fiducial approach
(Hacettepe University, Fac Sci, 2017)
In this study, we develop two simple generalized confidence intervals for the difference between means of two normal populations with heteroscedastic variances which is usually referred to as the Behrens-Fisher problem. ...
