Calculating the POWER in crossover study

Hi everyone, 

 

I'm working on a crossover study and I would like to calculate the power to detect the significant difference between the three periods.Is there any micro or codes that I can do that? 

 

The Crossover study has 3 periods and 6 sequences. 

Thanks

You may want to look at this paper. It discusses some of the details in using SAS Proc Power, whic is part of SAS/Stat to do power calculations for a couple of different crossover designs. http://www.pharmasug.org/cd/papers/SP/SP05.pdf

I have read this paper, but the macro is only for one sided t test. I'm looking for two sided t test.

Thanks
