We consider a framework for counterfactual statistical analysis with graphical models based on marked point processes. The main idea is to treat the counterfactual scenario as just another probability...

In this note, which develops a part of our paper [2], we
consider independence properties between Brownian motion, after
Brownian scaling on a random interval (a, b), and the length (b-a) of
the in...
