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 ...
Mean-Variance-Skewness-Entropy Measures: A Multi-Objective Approach for Portfolio Selection
(MDPI AG, 2011)
In this study, we present a multi-objective approach based on a mean-variance-skewness-entropy portfolio selection model (MVSEM). In this approach, an entropy measure is added to the mean-variance-skewness model (MVSM) to ...

Sürekli rassal değişken olarak kabul edilen rüzgâr hızı istatistiksel dağılımlarla karakterize edilir ve ortalama rüzgâr gücü tahminleri yapılır. Weibull dağılımı rüzgar enerjisi alanında kabul edilmiş dağılımdır. Ancak ...
Analysis of organizational commitment and work-family conflict in view of doctors and nurses
(Routledge Journals, Taylor & Francis LTD, 2012)
The present study investigates the relationship between organizational commitment and work-family conflict for medical doctors and nurses. Using canonical analysis on questionnaire, this relation has been tested distinctively ...
Modi?ed tests for comparison of group means under heteroskedasticity and non-normality caused by outlier(s)
(2017)
There are several approximate tests proposed such as Welch's F-test (W), the Parametric Bootstrap Test (PB) and Generalized F-test (GF) for comparing several group means under heteroskedasticity. These tests are powerful ...
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 ...
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 ...
Statistical Evaluation of Wind Characteristics in Kutahya, Turkey
(Taylor & Francis Inc, 2009)
The wind characteristics of a region have to be evaluated sensitively to benefit from the wind potential. For this aim, the wind potential in the Kutahya-Bunelek hill region has been determined using several statistical ...
Modelling Extreme Rainfalls Using Generalized Additive Models for Location, Scale and Shape Parameters
(Corvinus University Budapest, 2016)
This study aims to model the nonlinear relationship between the daily amount of extreme rainfall and significant predictor variables by the Generalized additive models for location, scale and shape parameters (GAMLSS). ...
