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 ...
Near optimal step size and momentum in gradient descent for quadratic functions
(Scientific Technical Research Council Turkey-Tubitak, 2017)
Many problems in statistical estimation, classification, and regression can be cast as optimization problems. Gradient descent, which is one of the simplest and easy to implement multivariate optimization techniques, lies ...
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 ...
Time Series Forecasting Using a Hybrid Neural Networks and Nonparametric Regression Model
(Isoss Publ, 2014)
The focus in this paper embraces the hybrid models whose components are nonparametric regression and artificial neural networks. Smoothing spline, regression spline and additive regression models are considered as the ...
Comparison of confidence intervals for the Behrens-Fisher problem
(Taylor & Francis Inc, 2017)
The Behrens-Fisher problem concerns the inferences for the difference between means of two independent normal populations without the assumption of equality of variances. In this article, we compare three approximate ...
Use of MinMaxEnt distributions defined on basis of MaxEnt method in wind power study
(Pergamon-Elsevier Science LTD, 2008)
Knowledge of the wind speed distribution is an important information needed in evaluation of wind power potential. Several statistical distributions have been used to study wind data. The Weibull distribution is the most ...
Multiple Comparison of Age Groups in Bone Mineral Density under Heteroscedasticity
(Hindawi Publishing Corporation, 2015)
Osteoporosis is a silent disease because individuals may not know that they have osteoporosis until their bones become so fragile. Bone mineral density (BMD) test helps to detect osteoporosis and determine the risk fractures. ...
Statistical power of an information-based test and its application to wave height data
(Pergamon-Elsevier Science LTD, 2010)
Modeling wave heights is crucial for many maritime applications. An appropriate statistical distribution for describing wave heights is the Rayleigh distribution. Estimating and testing the significance of the parameters ...
On the Identifiability of Finite Mixtures Based on the Union of Logarithmic Series and Discrete Rectangular Families
(Springer, 2009)
In this paper, finite mixtures of the union of Logarithmic Series and Discrete Rectangular families are proved to be identifiable. The sufficient condition for the identifiability of finite mixtures given by Atienza et al. ...
A new approach for estimating the parameters of Weibull distribution via particle swarm optimization: An application to the strengths of glass fibre Cheek tor data
(Elsevier Sci LTD, 2019)
Three-parameter Weibull is one of the most popular and most widely-used distribution in many fields of science. Therefore, many studies have been conducted concerning the statistical inferences of the parameters of Weibull ...
