研究人员推出了一种新颖的贝叶斯变量选择方法PliableBVS，该方法专为复杂的交互作用模型设计。该方法通过引入spike-and-slab先验来诱导稀疏性，从而扩展了pliable lasso，能够在统一的概率框架内同时选择主效应和交互作用效应。模拟研究表明，PliableBVS在识别显著效应、减少错误发现和提高预测准确性方面优于原始的pliable lasso。在与分娩发作和先兆子痫相关的研究中的实际应用表明，它能够精确定位具有生物学相关性的特征和交互作用。 AI
影响 引入了一种更强大的统计工具来分析复杂数据集，有可能改善各种科学应用中的特征选择。

High-dimensional interaction models are useful for studying, for example, how a large set of variables of interest, such as gene expression or other omics features, interact with a smaller set of modifying variables, such as clinical covariates. In this context, the pliable lasso…
