WebJul 22, 2024 · In this article, I suppose we have already obtained the estimated propensity scores for both treatment and comparison groups using the same data and following the procedures listed in my previous article (linked above). Before I dive into the nearest neighbor matching, below is the Python code for propensity score estimation. WebApr 13, 2024 · Nearest neighbor matching requires the specification of a distance measure to define which control unit is closest to each treated unit. The default and most common distance is the propensity score difference, which is the difference between the propensity scores of each treated and control unit (Stuart 2010).
