Four Factor Analysis Three Factors with Replication

We derive the analysis of variance for this situation from the complete four factor analysis given in Table 11,8. We have the T main effect, the first order interactions involving T and the second order interactions involving T, all non-

The arithmetic is lighter, however, if we total over all levels of A, i.e. sum over all replications, for each value of N, D, and R, thus getting a three factor table in which each figure is the sum of the replications.
