Abstract:

The present paper covers the Bayes estimation of the halfnormal distribution and compares the goodness of estimation under the quadratic loss function and the balance loss function. And it also proposes the similar result under Monte Carlo simulation and numerical simulation, and compares the differences of the estimations between different loss functions.

Key words: quadratic loss function, balance loss function, halfnormal distribution, Bayes estimation
