چکیده
In this paper, we study the preliminary test method in a linear regression model. The Liu-type estimator is introduced when it suspected that parameter may be constraint to subspace. We also compare estimator, ridge and Liu mean squared error sense.

Preliminary test almost unbiased ridge estimator in a linear regression model with multivariate Student-t errors
In this paper, the preliminary test almost unbiased ridge estimators of the regression coefficients based on the conflicting Wald (W), Likelihood ratio (LR) and Lagrangian multiplier (LM) tests in a multiple regression model with multivariate Student-t errors are introduced when it is suspected that the regression coefficients may be restricted to a subspace. The bias and quadratic risks of the...
متن کاملOn nonnegative garrote estimator in a linear regression model
Abstract: Subset selection regression is a frequently used statistical method. It waives some of the predictor variables and the prediction equation is based on the remaining set of variables. Subset selection is simple and it clearly reduces the variance. An other method for reducing the variance is ridge regression. Usually, subset selection is not as accurate as ridge. The problems with ridg...

متن کاملJackknifed Liu-type Estimator in Poisson Regression Model
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...
