As you can see, what Stein's estimator does is move each of the values closer to the grand average. It makes values greater than the grand average smaller, and values smaller than the grand average, greater.

網頁2024年9月5日 · The development of the James-Stein estimator, that addresses this paradox, has by now inspired a large literature on the theme of "shrinkage" in statistics. … 網頁So I think the question remains as to what is an intuitive reason that Stein's paradox does not appear in $\mathbb R$ and $\mathbb R^2$. I find very helpful a regression perspective offered in Stephen Stigler, 1990, A Galtonian Perspective on Shrinkage Estimators .
