Heterogeneity in treatment effects (HTE) analysis could enhance the original findings. Explore the presence of HTE in the SODIUM-HF trial using a risk-effect鈥揵ased approach. HTE was assessed using a risk-based approach based on the Meta-Analysis Global Group in Chronic (MAGGIC) HF risk ...
treatment-effect heterogeneity bias The focus of most estimation approaches is to eliminate the first type of bias, but also the second type of bias might threaten the validity of causal inference. Ben Jann (ETH Zurich) Heterogeneous Treatment Effect Analysis DSUG 2010 5 / 16 Introduction For...
在之前的文章中,我们主要聊的uplift模型,或者各种treatment effect的估计其实都focus在binary的情况,比如我们讨论发券不发券的因果效应,treatment T就是一个二元的,T=1表示发券,T=0表示不发。如果现在我们的问题变为发折扣率为多少的券带来的因果效应,这就变成了一个multi-valued或者continuous的问题了,如果你的折扣...
保持对effect heterogeneity建模的灵活性(通过随机森林、boosting、lasso和神经网络等技术),同时保留所学模型的因果解释,并同时提供有效的置信区间 使用统一的API 构建标准的Python包以用于机器学习和数据分析 机器学习最大的promise之一是在许多领域实现决策的自动化。许多数据驱动的决策场景的核心问题是对heterogeneous treat...
9 Briefly, the causal forest method keeps the main structure of random forest such as the recursive partitioning, subsampling, and random split selection, but the tree-splitting criteria are modified to suit the goal of HTE analysis, that is, maximizing the treatment effect heterogeneity—the ...
Our choice of a “building block” is governed by the counterfactual and the type of heterogeneity of interest. This object coincides with the “group-time average treatment effect” studied by Callaway and Sant’Anna (2020a) and is more granular than the building block used by Goodman-Bacon...

For therapies still in development or having their indications expanded, however, a clinical study may include a broader patient group but with evidence of treatment effect heterogeneity on clinical outcomes seen in different biomarker subgroups (e.g., varying outcomes in patients treated with PARP ...
In this study, we predicted the treatment effect heterogeneity of dexamethasone, the first choice of prophylactic antiemetics5, by applying machine learning-based causal models for observational data16,17,18,19,20. These models estimate the conditional average treatment effect (CATE) in a ...
通过探索不同的治疗方式、研发新的药物以及新的生物标志物,努力寻找解决这些问题的关键。“adaptive”,英文原意是指能够适应变化或者改变以适应新情况的能力,在抗肿瘤治疗中,“adaptive treatment(适应性治疗)”,即根据不同治疗场景的特征,在原有标准治疗方案的基础上...
