Expert sampling is particularly useful in epidemiology for several reasons:
1. Specialized Knowledge: Experts can provide valuable insights that might not be evident through other sampling methods. Their experience and expertise can help identify key variables, potential confounders, and relevant study populations. 2. Rare Conditions: In studies involving rare diseases or conditions, experts can help locate and select cases that would be difficult to identify through random sampling. 3. Rapid Assessments: Expert sampling can facilitate quick assessments in public health emergencies, allowing for timely interventions.
