Re: [Freesurfer] QDEC analysis with more that 2 fixed factors

Hi Molly, no one can really tell you that. My feeling is, that it is pretty safe, given that you have already 4 time points in the base. The base will be very stable and the main reason for the base is that it is an independent space different from any single time point. Which remains true.

Hi Matthieu, 1) survival analysis is typically used if you want to detect if the time to an event is longer in one group vs the other (e.g. one group gets placebo the other drug and we want to know if recurrence is later in the drug group). Not sure this is what you need. The nice thing is, it
