M-estimation of log-logistic distribution parameters with outliers
(DAV College, 2014)
Log-logistic distribution is widely-used in the analysis of agricultural, survival, hydrological and economics data. Therefore, its parameters have to be estimated accurately. Generally, traditional estimators such as ...
Parameter estimation using different information-theoretical divergence measures
(2006)
In this paper, a approach for parameter estimation is presented by using different divergence information measures. A comparison of the proposed approach and usual methods, such as the moment method, the least square method, ...
Comparison of Some Estimation Methods of the two parameter Weibull Distribution for Unusual
(2016)
Since the Weibull distribution has been accepted reference distribution in wind energy field, topics on its parameter estimation methods get much attention. In this context, the literature have generally focused on non-robust ...
A Monte Carlo simulation study on partially adaptive estimators of linear regression models
(Routledge Journals, Taylor & Francis LTD, 2011)
This paper presents a comprehensive comparison of well-known partially adaptive estimators (PAEs) in terms of efficiency in estimating regression parameters. The aim is to identify the best estimators of regression parameters ...
A comparative study for the location and scale parameters of the Weibull distribution with given shape parameter
(Pergamon-Elsevier Science LTD, 2008)
Nine parametric estimators of the location and scale parameters of a two-parameter Weibull distribution are compared in terms of their bias and efficiency in a simulation study. The estimators considered are the maximum ...
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 ...
Farklı Olasılık Yoğunluk Fonksiyonları Kullanarak Rüzgar Gücü Potansiyelinin Tahmini
(2016)
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 ...
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 ...
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 ...
On the performance of the flexible maximum entropy distributions within partially adaptive estimation
(Elsevier Science BV, 2011)
The partially adaptive estimation based on the assumed error distribution has emerged as a popular approach for estimating a regression model with non-normal errors. In this approach, if the assumed distribution is flexible ...
