HI All:

Can anyone give me the formulae/steps for calculating the type III sum of
squares for an unbalanced 2-way ANOVA design?  Eg. we are looking at 8
treatments x 4 doses, with unequal numbers of replications within the
groups.  I really need the stepwise calculation, as I would try to put it
in my own code (possibly in Visual Basic) to automate the task.

Thanks very much.

Karth.
