病例对照研究贝叶斯分析中前瞻与回顾模型的等价性AI 解读

The natural likelihood to use for a case‐control study is a ‘retrospective’ likelihood, i.e. a likelihood based on the probability of exposure given disease status. Prentice & Pyke (1979) showed that, when a logistic regression form is assumed for the probability of disease given exposure, the maximum likelihood estimators and asymptotic covariance matrix of the log odds ratios obtained from the retrospective likelihood are the same as those obtained from the ‘prospective’…

含分类协变量的病例对照研究贝叶斯分析AI 解读

In a case‐control study the appropriate likelihood is the ‘retrospective’ likelihood, i.e. the likelihood of exposure given disease. For the classical frequentist analysis, the ‘prospective’ likelihood, i.e. the likelihood of disease given exposure, and the retrospective likelihood produce the same odds‐ratio estimators for exposure, and so logistic regression may be used for both. The Bayesian analysis is not so simple, but the Bayesian framework for case‐control studies…
