For other than the basic situations I generally use simulation to
estimate power. Follow these basics steps:
Write a function that takes as input the things that you may want to
change in estimating power (sample size, effect size, standard
deviations, ...). Inside the function generate random d

If you are capable of installing source packages and if you know what a
general linear hypothesis test is, you can:
download 'hpower' to your computer

Indeed, it does so on both my Ubuntu and Win XP boxes. The problem i
