Hi,
I need an advice:
I would like to compare paired observations (pre- and post-treatment
measures)to a fixed value: does the change between pre and post values is
significantly higher than 50?
First I thank to use a classical paired t test, but I would like to use an
adjustment covariate (to take into account an important factor).
What is the correct method to use?
If I use an analysis of covariance:
pre = post + covariate
which part of the results will give me the answer related to the fixed
value 50?
Thanks for your replies
