Abstract

Suggests that the most useful statistical techniques for practical prediction problems, as in personnel selection, may be 2 new techniques, ridge regression and Stein-type regression. They combine the sensitivity of multiple regression with the resistance to sampling error of other techniques--notably rational (clinical) weights and weights determined by simple correlations. However, the new techniques are not recommended for theoretical modeling work, since they yield biased estimates of the true least squares weights, typically have higher expected squared errors for estimating some weights, and do not allow the use of ordinary confidence bands or significance tests.
