Robust Estimation With the Skew T(2) Distribution
(Isoss Publ, 2013)
In this paper, a skew extension of the Student's t distribution with two degrees of freedom is used to model data sets that have skewness and heavy-tails. Its parameters are estimated using two different approaches based ...
ROBUST 2(k) FACTORIAL DESIGNS: NON-NORMAL SYMMETRIC DISTRIBUTIONS
(Isoss Publ, 2012)
Senoglu (2005, 2007a) considered the estimation and hypothesis testing procedures for the 2(k) factorial designs when the error distributions are skew. They obtained the modified maximum likelihood (MML) estimators of the ...
Robust estimation with the skew t2 distribution
(2013)
In this paper, a skew extension of the Student's t distribution with two degrees of freedom is used to model data sets that have skewness and heavy-tails. Its parameters are estimated using two different approaches based ...
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 ...
Alpha-skew generalized t distribution [Distribución t generalizada alfa sesgada]
(Universidad Nacional de Colombia, 2015)
The alpha-skew normal (ASN) distribution has been proposed recently in the literature by using standard normal distribution and a skewing approach. Although ASN distribution is able to model both skew and bimodal data, it ...
One-step M-estimators: Jones and Faddy's skewed t-distribution
(Taylor & Francis LTD, 2013)
One-step M (OSM)-estimator needs some initial/preliminary estimates at the beginning of the calculation process. In this study, we propose to use new initial estimates for the calculation of the OSM-estimator. We consider ...
İki-fazlı doğrusal regresyon modelinde değişim noktasının dayanıklı tahmini
(Anadolu Üniversitesi, 2014)
Bu tez çalışmasında, iki-fazlı doğrusal regresyon modelinde değişim noktasının tahmini ele alınmıştır. İki-fazlı doğrusal regresyon modelindeki hata terimlerinin dağılımının uzun kuyruklu simetrik (long-tailed symmetric–LTS), ...
Ortak değişkenlerin varlığı durumunda faktöriyel tasarımlar
(Anadolu Üniversitesi, 2010)
Bu calışmada ortak değişkene sahip faktöriyel tasarımlar ele alınmıştır. Bu tasarımlar için klasik teori, normallik varsayımına dayalı elde edilir. Buna karşın, hata terimleri normal dağılıma sahip değilse model parametrelerinin ...
