Before revision:  We present accurate linear and deep-learning counterfactual prediction modelswhich achieve respectively 1.1\% and 1 \% of error  and allow to estimate a simulated effect quite accurately .
After revision:  We present accurate linear and deep-learning counterfactual prediction modelswhich achieve respectively 1.1\% and 1 \% of error and allow to accurately estimate small impacts (in the order of 2\%) .
