BOUNDING THE LOCAL AVERAGE TREATMENT EFFECT IN AN INSTRUMENTAL VARIABLE ANALYSIS OF ENGAGEMENT WITH A MOBILE INTERVENTION.

ABSTRACT: Estimation of local average treatment effects in randomized trials typically relies upon the exclusion restriction assumption in cases where we are unwilling to rule out the possibility of unmeasured confounding. Under this assumption, treatment effects are mediated through the post-randomization variable being conditioned upon, and directly attributable to neither the randomization itself nor its latent descendants.
