Abstract:
|
Most existing methods for surrogate outcomes in randomized trials fall into one of two paradigms: the causal effects paradigm and the causal association paradigm. The paradigms are complementary, with each dealing with some weaknesses in the other. These paradigms are readily extended to observational studies and time-varying treatments. Further, each one is relevant to characterizing the effects of partially manipulable variables.
