Abstract
External validation helps to assess whether a given risk prediction model will perform well in a target population. Validation is an important step in maintaining the utility of risk prediction models, as their ability to provide reliable risk estimates will deteriorate over time (calibration drift).
摘要
外部验证有助于评估给定的风险预测模型在目标人群中是否会表现良好。验证是维持风险预测模型效用的重要一步，因为它们提供可靠风险估计的能力会随着时间推移而下降（校准漂移）。
