岭回归估计量的新高斯近似

研究人员开发了一种新颖的高斯近似方法,用于岭回归估计量的有限样本分布。该近似考虑了估计量在减少误差方面的偏差-方差权衡,并且基于非标准渐近理论,其中正则化参数随样本量增长,总体系数局部于参考向量。该方法能够处理数据中的一般异方差性和自相关性,并被用于提出两种新的正则化参数选择策略,以最小化预测风险。 AI

影响 这项研究为分析回归估计量提供了一种改进的统计方法,有可能提高计量经济学和机器学习背景下模型的准确性。

    Ridge回归估计量分布的简单近似

    arXiv:2608.02539v1 Announce Type: cross Abstract: We present a simple Gaussian approximation to the finite-sample distribution of the classical ridge regression estimator. Our approximation captures the fact that, in finite samples, the ridge regression estimator trades off bias …
