RE: NBS Statistical Test button - One Sample
Hi Teena Moody,
Regarding the one-sample test, here is the relevant text from the NBS manual:
"The one sample test randomly flips the sign of each data point for each permutation, which corresponds to a one-sided, one-sample t-test. Note that the one sample test always assesses whether the mean is greater than zero, irrespective of the sign of the contrast vector."

Thanks for the reply. I really want to know what the one sample button is for.
I have had success doing t-tests between groups, for example, looking at the NBS results for CON vs PATIENT groups using the contrasts [1,-1] and [-1,1], and for anovas.
Can NBS also be used to identify the "strongest" networks within a single group? I thought perhaps that was what the one sample button was for. I couldn't find this option mentioned in the documentation.
Also is the pair-wise option available?
Thank you!
