Improved Liu-type estimator in partial linear model
International Journal of Computer Mathematics, 2015In this article, a Liu-type estimation is proposed for the vector-parameter in a partial linear model. This new estimator can be regarded as generalization of the restricted least-squares estimator, the restricted ridge estimator and the restricted Liu estimator. We also obtain the asymptotic distributional bias and risk of these estimators and we also

Liu-type estimator in semiparametric regression models
Journal of Statistical Computation and Simulation, 2009In this paper, we introduced a Liu-type estimator for the vector of parameters β in a semiparametric regression model. We also obtained the semiparametric restricted Liu-type estimator for the parametric component in a semiparametric regression model. The ideas in the paper are illustrated in a real data example and in a Monte Carlo simulation study.

MODIFICATION OF LIU-TYPE ESTIMATOR FOR TWO SUR MODEL
Advances and Applications in Statistics, 2019Summary: In this paper, we suggest a new biased Liu-Type estimator for the vector of parameters in a two SUR model. This Liu-type two SUR estimator based on ridge estimation. Furthermore, the superiority of this estimator from the ridge estimator and Liu-Type estimator was verified by mean square error (MSE).

Improvement of the Liu‐type Shiller estimator for distributed lag models
Journal of Forecasting, 2017AbstractThe problem of multicollinearity produces undesirable effects on ordinary least squares (OLS), Almon and Shiller estimators for distributed lag models. Therefore, we introduce a Liu‐type Shiller estimator to deal with multicollinearity for distributed lag models.

On the weighted mixed Liu-type estimator under unbiased stochastic restrictions
Communications in Statistics - Simulation and Computation, 2017AbstractIn this article we introduce the weighted mixed Liu-type estimator (WMLTE) based on the weighted mixed and Liu-type estimator (LTE) in linear regression model. We will also present necessary and sufficient conditions for superiority of the weighted mixed Liu-type estimator over the weighted mixed estimator (WME) and Liu type estimator (LTE) in ...
