one-sample t test for NBS
Dear Andrew,
First of all, thank you for this very nice tool! I would like to
ask something about the underlying process of the one sample
t-test. What is written in the manual is: "The one sample test
randomly flips the sign of each data point for each
permutation".
In my study, I chose the t-test button. In resting state fmri analysis, using the NBS, find the edges and nodes where FC is related to behavior. However, the subjects were not grouped. The first column of the design matrix is the value of the behavioral variable, the next three columns are the values of the covariates, the contrst is [1 0 0 0], and the threshold is 3.1. Is it ok to set it up like this?
