Hi,
Brief description of my problem: My data consists of physiological data from animal experiments. For each animal I have conducted multiple experiments and the data are best described by linear regression. I wish to compare the regression coefficients (slopes) between my 4 groups.
I've attached an illustration that describes my problem (only 2 groups displayed though). The lines of same color are from experiments conducted on the same animal.
Which statistical test is appropriate for this problem?
Thank you.
