Identifying Patient-Specific Root Causes with the Heteroscedastic Noise Model
利用异方差噪声模型识别患者特定的疾病根因
Complex diseases are caused by a multitude of factors that may differ between patients even within the same diagnostic category. A few underlying root causes may nevertheless initiate the development of disease within each patient. We therefore focus on identifying patient-specific root causes of disease, which we equate to the sample-specific predictivity of the exogenous error terms in a structural equation model. We generalize from the linear setting to the…
