Abstract
An improved method of estimating the coefficient in Fairfield Smith''s empirical relationship between plot size and variability is described and illustrated on data from an agricultural field trial. The coefficient is determined from a weighted regression in which the weighting takes into account the correlations and unequal variances of the variance estimates.This publication has 1 reference indexed in Scilit:
