Are independent chi-square random variables with degrees of freedom fi. Satterthwaite (1946) approximates the distribution of Z2 by that of cχ2f.
These results can be related to Satterthwaite’s approximation in equation 18.17 by appropriate definitions of ϵiand substitution of observed mean squares for unknown variances.
