Best answer

Another popular approach is (propensity score) weighting 

Main idea:

Re-weigh the treatment and control groups to create a pseudo-population—the target population—where the two groups are balanced, in expectation

A general class of balancing weights

Different weighting schemes: different target population and causal estimands

One should choose the target population a priori
