The tpsPower program was written mostly just to perform the simulations used in my paper comparing power surfaces of various morphometric methods in testing for a difference in two mean shapes.
I tried to also make it useful for some practical planning of a morphometric study but it is someshat limited for that as it only allows the specification of a simple error structure. That could be generalized if users thought it would be useful. -------- Sent remotely by F.

Is it true to say that, in terms of power calculation, tpsPower is designed to estimate statistical power for testing the difference between two mean shapes? 2. Is it also true to say that tpsPower is not designed for determining the equivalence between two measurements? Sorry if I'm missing something simple here - Dave -- Replies will be sent to the list.
