Robust Liu‐type estimator based on GM estimator

Statistica Neerlandica, 2023
Ordinary Least Squares Estimator (OLSE) is widely used to estimate parameters in regression analysis. In practice, the assumptions of regression analysis are often not met. The most common problems that break these assumptions are outliers and multicollinearity problems. As a result of these problems, OLSE loses efficiency.

New modified two-parameter Liu estimator for the Conway–Maxwell Poisson regression model

Journal of Statistical Computation and Simulation, 2023
The Conway–Maxwell–Poisson (COMP) model is one of the count data regression models used in over- and underdispersion cases. Thus, COMP regression is a flexible model in the count data models. In the regression analysis, when the explanatory variables are

Extending the Liu estimator for the Cox proportional hazards regression model with multicollinearity

Communications in statistics. Simulation and computation, 2023
In this article, we present the Liu estimator for the Cox proportional hazards (PH) model. The maximum partial likelihood estimator (MPLE) is commonly used for estimation of the coefficients of the Cox PH model.

Restricted Liu estimator under stochastic linear restrictions in generalized linear models: theory and applications

Communications in statistics. Simulation and computation, 2023
It is a fact that the problem of multicollinearity adversely effects the estimation of parameters not only in normal linear models but also in generalized linear models (GLMs).

A modified one parameter Liu estimator for Conway-Maxwell Poisson response model

Journal of Statistical Computation and Simulation, 2022
The maximum likelihood estimator (MLE) is generally used to estimate the Conway Maxwell Poisson regression model (COMPRM). When the explanatory variables are highly correlated, then the MLE results are not valid. In this study, we proposed a modified one-

A new improved Liu estimator for the QSAR model with inverse Gaussian response

Communications in statistics. Simulation and computation, 2022
The regression model is one of the important quantitative structure-activity relationship (QSAR) model tools that is used chiefly in chemometrics studies.

A robust Liu regression estimator

Communications in Statistics - Simulation and Computation, 2017
The least-squares regression estimator can be very sensitive in the presence of multicollinearity and outliers in the data. We introduce a new robust estimator based on the MM estimator.
