错误指定线性模型中的高维推断

High-dimensional inference in misspecified linear models

Peter Bühlmann, Sara van de Geer

摘要:

当假设的线性模型被错误指定时,我们考虑高维推理。我们描述了一些正确的解释和相应的充分假设,有效的渐近推断的模型参数,这仍然有一个有用的意义时,模型是错误的。我们主要集中在去稀疏化的Lasso过程,但我们也表明(多)样本分裂技术的一些影响。鉴于现有的方法和软件,我们的研究结果有助于鲁棒性考虑模型误设定。

英文摘要:

We consider high-dimensional inference when the assumed linear model is misspecified. We describe some correct interpretations and corresponding sufficient assumptions for valid asymptotic inference of the model parameters, which still have a useful meaning when the model is misspecified. We largely focus on the de-sparsified Lasso procedure but we also indicate some implications for (multiple) sample splitting techniques. In view of available methods and software, our results contribute to robustness considerations with respect to model misspecification.
