Generalized entropy optimization distributions dependent on parameter in time series
(2010)In this paper, we have proposed Generalized Entropy Optimization Problems (GEOP) concerned with parameters which consist of maximizing Entropy Functional subject to constraints dependent on parameters. Therefore, MinMaxEnt ... -
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 ... -
Generalized Least Squares and Weighted Least Squares Estimation Methods for Distributional Parameters
(Inst Nacional Estatistica-Ine, 2015)Regression procedures are often used for estimating distributional parameters because of their computational simplicity and useful graphical presentation. However, the resulting regression model may have heteroscedasticity ... -
Generalized Lindley and Power Lindley distributions for modeling the wind speed data
(Pergamon-Elsevier Science LTD, 2017)In this study, we propose to use Generalized Lindley (GL) and Power Lindley (PL) distributions as an alternative to the Weibull distribution for modeling the wind speed data. In the application part of the study, we consider ... -

Görünüşte ilişkisiz regresyon denklemlerinin genelleştirilmiş en küçük kareler yöntemiyle kestirimi
(1998)Görünüşte ilişkisiz regresyon denklemlerinin kestiriminde kullanılan çeşitli yöntemler vardır. Bunlardan biri olan genelleştirilmiş en küçük kareler yöntemi, hataların aynı zamanda ilişkili olduğu, ancak otokorelasyon ... -
A group sequential test of circular data using the von Mises distribution
(Hacettepe University, Fac Sci, 2015)In this study, the group sequential test is suggested for the mean direction parameter of the von Mises distribution when the concentration parameter is known and unknown. An application of the proposed test is illustrated ... -
An improved version of backpropagation algorithm with effective dynamic learning rate and momentum
(2006)An improvement of backpropagation algorithm with momentum is introduced. Local quadratic approximation of the error function is performed at every stage of the learning process and the Hessian matrix of the quadratic error ... -
The individuals control chart in case of non-normality
(2006)This article examines the effects of non-normality as measured by skewness and provides an alternative method of designing individuals control chart with non-normal distributions. A skewness correction method for constructing ... -
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 ... -
Inferences on stress-strength reliability based on ranked set sampling data in case of Lindley distribution
(Taylor & Francis LTD, 2018)In this study, we consider point and interval estimation of stress-strength reliability R = P(X < Y) based on ranked set sampling when the distribution of the stress and the strength are both Lindley. Firstly, maximum ... -
An innovative estimation method regarding Weibull parameters for wind energy applications
(Pergamon-Elsevier Science LTD, 2016)Two-parameter Weibull distribution is widely-used and accepted as the most popular distribution for the evaluation of wind energy potential. However, it is well-known that parameter estimates have significant effects on ... -
Interval estimation of the system reliability for Weibull distribution based on ranked set sampling data
(Hacettepe University, Fac Sci, 2018)Inference for the system reliability R is one of the most popular problems in the areas of engineering, statistics, biostatistics and etc. Therefore, there exist considerable numbers of studies concerning this problem. ... -
Interval Type-2 Fuzzy Analytic Network Process for Modelling a Third-party Logistics (3PL) Company
(Old City Publishing Inc, 2017)The Fuzzy Analytic Network Process (ANP) is generally used for solving multi-criteria decision making (MCDM) problems by considering the pairwise comparison between criteria/sub-criteria, and inner/outer dependencies among ... -
Interval Type-2 Fuzzy c-Control Charts: An Application in a Food Company
(Inst Mathematics & Informatics, 2017)Many papers exist on ordinary fuzzy control charts in literature in order to consider the vagueness and uncertainty in observation data. These are on both variable and attribute control charts. Several extensions of fuzzy ... -
