Matching Intuition 🌱

  • Propensity score matching is like trying to turn an observational study into a purely randomized experiment with random treatment assignment
  • Other matching methods like exact matching try to turn an observational dataset into a randomized blocked experiment where we block by covariates and then randomize. This is a more powerful experiment.
