Pitman Closeness in Classes of General Pre-Test Estimators and Regression Estimators

We prove transitivity and other useful properties for the Pitman closeness criterion within the class of general pre-test estimators (PTE). As an application, we compare the ordinary least squares estimator with th...

Optimal pre-test estimators in regression

Pre-testing in a linear regression model is studied. Optimality under a general quadratic loss function and a general prior for the coefficient is discussed....

Asymptotic behaviour of regression pre-test estimators with minimal Bayes risk

Pre-test estimators (PTE) are considered which are optimal under a Bayes risk among PTE with general measurable sets as “regions of significance” for the test statistic t associated with the estimat...

Optimization of regression models: some numerical results

The problem of an optimal choice of a regression model is discussed. With one regressor being considered for omission, traditional and optimal pre-test estimators and also some shrinkage estimators are numerically ...
