英文摘要
In this research, assuming the quadratic and non-quadratic loss functions, we formulate the alternative risk functions, and examine the risk performances of the shrinkage and pre-test shrinkage estimators. We derive the exact formulas of the risk functions, and show various properties of the risk functions of shrinkage and pre-test shrinkage estimators under alternative loss functions.
