Testing for differences in amplitude and phase
...# there is probably a more elegant solution omega2Day=omega2*Day m=lme(y~(cos(omegaDay)+sin(omegaDay)+cos(omega2Day)+sin(omega2Day))*treatment, random=~1|subject) summary(m) The summary table tells me that the respective elements are significant (except for cos(omegaDay):treatmentTRUE). I know how to calculate the amplitudes and phases for both treatment groups from the model estimates, but how do I know if they are significantly different? Thanks to anyone who takes the time to help me with this problem! Karin _________________________________________...
