个体处理效应的共形预测区间

Conformal prediction intervals for the individual treatment effect

Danijel Kivaranovic, Robin Ristl, Martin Posch, Hannes Leeb

摘要:

我们提出了几个预测区间的个人处理效应与有限样本或渐近覆盖保证在非参数回归设置,其中允许非线性回归函数,异方差和非高斯。我们使用Vovk等人(2005)的保形方法构建预测区间。在广泛的模拟中,我们比较了我们的预测区间过程的覆盖概率和区间长度。我们证明,复杂的学习算法,如神经网络,可以导致更窄的预测区间比简单的算法,如线性回归,如果样本量是足够大的。

英文摘要:

We propose several prediction intervals procedures for the individual treatment effect with either finite-sample or asymptotic coverage guarantee in a non-parametric regression setting, where non-linear regression functions, heteroskedasticity and non-Gaussianity are allowed. The construct the prediction intervals we use the conformal method of Vovk et al. (2005). In extensive simulations, we compare the coverage probability and interval length of our prediction interval procedures. We demonstrate that complex learning algorithms, such as neural networks, can lead to narrower prediction intervals than simple algorithms, such as linear regression, if the sample size is large enough.
