Hi,
I have a few questions about the F-test described here:
http://www.fmrib.ox.ac.uk/fsl/feat5/detail.html
- "Also, the F-test allows you to compare the contribution of each
contrast to the model and decide on significant and non-significant ones."
Do we need a few F-tests to do this? each F-test tells how significant
each contrast is?
- "One example of F-test usage is if a particular stimulation is to be
represented by several EVs ..."
Several original EVs? real EVs?
And, how are the fstat and zfstat related?
Is zfstat the right thing to enter higher level (e.g., group) analysis?
Thanks,
George
