in this research between 3-dimensional and axisymmetric modeling for movement of nano-particles in passing through a aerodynamic lens, and also between these models and famous model of wang & liu was compared. for this purpose, output of nano-particles penetration, divergence angel, and nano-particle velocity with wang & liu model was compared. geometrical model used for aerodynamic lens compar...
The Liu estimator has consistently been demonstrated to be an attractive shrinkage method for reducing the effects of multicollinearity. The Poisson regression model is a well-known model in applications when the response variable consists of count data. However, it is known that multicollinearity negatively affects the variance of the maximum likelihood estimator (MLE) of the Poisson regressio...
The Liu-type estimator is one of the shrink estimators that used to remedy for a problem multicollinearityin SUR model, but it sensitive outlier. In this paper, we introduce S (SLiu-type) and MM (MMLiu-type) model. These merge with S-estimator MM-estimator which makes have high robustness at different level efficiency same time prevents bad effects multicollinearity. Moreover, get more robust f...
