Note: “SNF (logistics)” represents the probability of observing a positive SNF cost (e.g., discharge to SNF), “SNF (GLM)” represents the amount of SNF spending conditional on discharge to SNF, and “average adjusted cost” represents the marginal effects for the combined logit and GLM version of the two‐part model.
