I am comparing two populations (the PET models version) with f contrast
[1 -1] (hypothesizing that ill group has lower metabolism) and when I try
to retrieve the text metabolism levels (by typing xY.Y) at the MATLAB
prompt, I get an output with positive and negative numbers. Why are they
positive and negative instead of just a range of positive numbers (some
with lower metab and some with higher)?
Thank you very much,
Meghan Fusz
