Estimating Treatment Effects using Multiple Surrogates: The Role of the Surrogate Score and the Surrogate Index

arXiv:1603.09326v4 Announce Type: replace-cross
Abstract: Estimating the long-term effects of treatments is of interest in many fields. A common challenge in estimating such treatment effects is that long-term outcomes are unobserved in the time frame needed to make policy decisions. One approach to overcome this missing data problem is to analyze treatments effects on an intermediate outcome, often called a statistical surrogate, if it satisfies the condition that treatment and outcome are independent conditional on the statistical surrogate. The validity …
