The relationship between causal effects ATT, ATE and propensity score is as follows: ATE: test group: Control group: It is the probability score calculated by the model.
ATT: test group: Control group: So far, we have calculated the weight coefficient w. Gain effect assessment By inserting the above formula, ATT or ATE can be calculated. 3. The application of propensity-weighted score in the quantitative gain of activity ws number list effect The following takes participation in an activity as an example to explain the application of the propensity-weighted scoring method to the quantitative gain of activity ROI.
1. Division of experimental group and test group The causal inference is essentially artificially simulating the AB Test, so the simulated AB groups should also meet the definition of the real AB test grouping.
