Jackknifed 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...

Maximum Weighted Likelihood Estimator in Logistic Regression

The least weighted squares estimator is a well known technique in robust regression. Its likelihood analogy in logistic regression is the maximum weighted likelihood estimator, proposed in Vandev and Neykov (1998) and Mueller and Neykov (2003). This article mentions already proved properties, shows its inconsistency and compare it to the other estimators by an extensive simulation. Introduction...

Combining the Liu-type Estimator and the Principal Component Regression Estimator

In this study a new two-parameter estimator which includes the ordinary least squares (OLS), the principal components regression (PCR) and the Liu-type estimator is proposed. Conditions for the superiority of this new estimator over the PCR, r-k class estimator and Liu-type estimator are derived. Furthermore the performance of this estimator is compared with the other estimators in different co...

Implementing the Bianco and Yohai estimator for logistic regression

In 1996, Bianco and Yohai proposed a highly robust estimation procedure in the logistic regression model. The theoretical results they obtain were very promising. In this paper we complement their study by providing a fast and stable algorithm to compute this estimator. Moreover, we derive criteria for the existence of the estimator at finite samples and discuss the problem of the selection of ...

On almost unbiased ridge logistic estimator for the logistic regression model

Schaefer et al. [15] proposed a ridge logistic estimator in logistic regression model. In this paper a new estimator based on the ridge logistic estimator is introduced in logistic regression model and we call it as almost unbiased ridge logistic estimator. The performance of the new estimator over the ridge logistic estimator and the maximum likelihood estimator in scalar mean squared error cr...
