Robust modified jackknife ridge estimator for the Poisson regression model with multicollinearity and outliers

Robust modified jackknife ridge estimator for the Poisson regression model with multicollinearity and outliers

The parameters in the Poisson regression model are usually estimated using the maximum likelihood estimator (MLE). MLE suffers a breakdown when there is either multicollinearity or outliers in the Poisson regression model. The ridge estimator and the modified jackknife ridge estimator are generally...
