Sample Size and the Accuracy of Predictions Made from Multiple Regression Equations.
Sawyer, Richard
Journal of Educational Statistics, v7 n2 p91-104 Sum 1982
Rules are given for estimating accuracy of predictions based on a multiple regression equation. Formulas for moments of distribution and other parameters are noted. The approximate inflation in mean absolute error due to estimating the regression coefficients is a function of the base sample size and number of predictors. (DWH)
