Which is the best propensity model to use?
Not all propensity models are created equal. The first step is to actually pick a model because you have a few options. For example, instead of measuring propensity to churn, you could choose a survival analysis. Regression is a good option because it’s very interpretable for non-technical audiences, which means it can be communicated easily.
What’s the cutoff for a propensity score?
Typically, 0.01 is chosen for a cutoff. The ratio of exposed to unexposed subjects is variable. 1:1 matching may be done, but oftentimes matching with replacement is done instead to allow for better matches.
