Permutation Testing for One Group/Time Point
Apologies if this question has already been answered in the
forum.
I'm aware that permutation testing with two groups involves randomly exchanging data points from sample A with data points from data B but I am wondering how this works for a one-sample t-test.
For example, I have a single patient group and am examining how a measure of change in symptom scores correlates with connectivity at time point 1, using a a contrast of [0 -1] for negative correlation and a contrast of [0 1] for positive correlation. Wondering how the permutation testing actually works for this single group.
