Joint Modelling of Location, Scale and Skewness Parameters of the Skew Laplace Normal Distribution
Fatma Zehra Doğru, Olcay Arslan
In this article, we propose joint location, scale and skewness models of the skew Laplace normal (SLN) distribution as an alternative model for joint modelling location, scale and…
Double Reweighted Estimators for the Parameters of the Multivariate t Distribution
Fatma Zehra Doğru, Y. Murat Bulut, Olcay Arslan
The t-distribution has many useful applications in robust statistical analysis. The parameter estimation of the t-distribution is carried out using ML estimation method, and the ML…
Robust mixture regression based on the skew t distribution
Fatma Zehra Doğru, Olcay Arslan
In this study, we propose a robust mixture regression procedure based on the skew t distribution to model heavy-tailed and/or skewed errors in a mixture regression setting. Using t…
Robust mixture regression modeling based on the Generalized M (GM)-estimation method
Fatma Zehra Doğru, Olcay Arslan
Bai (2010) and Bai et al. (2012) proposed robust mixture regression method based on the M regression estimation. However, the M-estimators are robust against the outliers in respon…
