Dear SPMers:
I am using spm99 to analyze PET data. I need some help in selecting
statistic model.
I have two groups (normal controls & patients). There is only 1
scan/subject. Also we have some behavioral parameters (RT,accuracy
etc) during the scan. I have used the compare-populations:1
scan/subject (two sample t-test) to compare the difference in brain
activity between the two groups. I would like to see how this
difference relates to the difference in behavioral performance(RT and
Accuracy).In other words, I would like to calculate the correlation
between difference in brain activity and difference in behavioral
parameters between the two groups. Which is the most appropriate
model that I should use for this?
Any suggestion would be appreciated.
Sincerely,
Yun
