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 ...
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 ...
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 ...
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 ...
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 ...
Assessing the Quality of the Natural Cubic Spline Approximation
(World Scientific Publ Co Pte LTD, 2009)
In large samples, central limit and saddle-point approximation theory suggest that spline functions having just two or three knots may be used to approximate the log- likelihood function for a single parameter, with the ...
A Statistical Investigation on Wind Energy Potential of Northwest of Turkey
(IEEE, 2016)
The northwest of Turkey is an important region which is a rapidly developing industrial center. Thus, energy analysis of this region has a high importance for the region's geopolitical, economic and demographic structure. ...
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 ...
