Hi Rich, okay i'll post the reason why I ask:
It is because I am validating a 24hr dietary recall questionnaire
using
a food frequency questionnaire:
as someone else pointed out i got an error, also a perfect correlation
for pearsons.
it is much more complicated than this but that is the scoop.
Amazingly I got a perfect correlation between the two, you would think
that the 24hr would be at least a bit attenuated but I got a perfect
correlation or "error"
