Selection Mechanism and Their Consequences: Understanding and Addressing Selection Bias

Understanding the way in which a study sample relates to the target population is critical for avoiding and addressing bias. Communication about selection bias is aided by the use of causal graphs.

Simple Sensitivity Analysis for Control Selection Bias

We extend a sensitivity analysis approach for selection bias to account for poor control selection in case-control studies.

Bounding Bias Due to Selection

We provide bounds for selection bias under a variety of situations.
