## Mean Vector Estimation

Estimation of mean vector is a classical problem which includes Stein’s paradox. There are many approahces in estimating mean vecotr such as linear estimator and approximate Bayes estimator using nonparametric empirical Bayes or nonparametric maximum likelihood estimation. Efron (2014) categorized nonparametric empirical Bayes
estimation by introducing f-modeling and g-modeling. Its application area is very broad including small area estimation and high dimensional classification.
