LLASSO: A linear unified LASSO for multicollinear situations
M. Arashi, Y. Asar, B. Yuzbasi
We propose a rescaled LASSO, by premultipying the LASSO with a matrix term, namely linear unified LASSO (LLASSO) for multicollinear situations. Our numerical study has shown that t…
Some theoretical results on tensor elliptical distribution
M. Arashi
The multilinear normal distribution is a widely used tool in tensor analysis of magnetic resonance imaging (MRI). Diffusion tensor MRI provides a statistical estimate of a symmetri…
Preliminary testing derivatives of a linear unified estimator in the logistic regression model
Yasin Asar, Bahadır Yüzbaşı, Mohammad Arashi +1
Recently, the well known Liu estimator (Liu, 1993) is attracted researcher's attention in regression parameter estimation for an ill conditioned linear model. It is also argued tha…
A sure independence screening procedure for ultra-high dimensional partially linear additive models
M. Kazemi, D. Shahsavani, M. Arashi
We introduce a two-step procedure, in the context of ultra-high dimensional additive models, which aims to reduce the size of covariates vector and distinguish linear and nonlinear…
On the restricted almost unbiased Liu estimator in the Logistic regression model
Jibo Wu, Yasin Asar, M. Arashi
It is known that when the multicollinearity exists in the logistic regression model, variance of maximum likelihood estimator is unstable. As a remedy, in the context of biased shr…
