Connectivity density as outcome
REGRESSION
In this section we detail why we reversing the predictor/response relationship is a compelling idea and thus compare the results with a typical function‐on‐scalar regression with connectivity densities as outcomes.Excepting the convenience, as discussed in Section Consider the following typical linear functional model with outcome function In Figure Estimated difference function of the transformed neural densities between treatment and control groups, holding all other variables the same. Similar patterns could be found compared with Figure Figure A sample outcome function from the fitted model. It breaks the positive constraints on both tails and its integral is
