I have a quick question on generating p-values from datasets in AFNI.
I have a 3 3dDatasets. One dataset contains coefficients (X), one contains the mean (Mu), the other contains standard deviation (SD). I would like to get the corresponding p-value (2-tailed) for these values. I’ve modeled my 3dcalc code after SAS commands, where the pvalues would correspond to one half of the distribution as:
and the other half is:
depending on whether or not X is greater than Mu or not.
My question is, am I using the 3dcalc command correctly here, or am I overcomplicating the cdf command? I would use code 2 , but the coeffecient is not a correlation coeffecient.
Thank you and apologies if I am being confusing!
