Dear SPMers,
we're attempting to conduct a parametric analysis.
We have two condition A(experimental condition) B(control condition); in the
experimental condition the parameter assumes 3 different values.
1) Which is the difference between choosing a polynomial or a linear
relationship in the model?
2) In the results session how can we specify the contrast for the AB
difference? and for the parameter effect on the experimental condition?
Thanks in advance
