Distribution of the shrinkage parameters in different scenarios and sample sizes.

Data represent median values as well as 1st and 3rd quartiles of the cross-validated tuning parameters for n = 50, 110 and 500 and both simulation scenarios. Ridge method (Ridge); least absolute shrinkage and selection operator (LASSO); elastic net L1-L2 (Enet 1), elastic net L2-L1 (Enet 2), elastic net L1+L2 (Enet 3).Distribution of the shrinkage parameters in different scenarios and sample sizes.

本数据集收录了n=50、110、500三种样本量与两种模拟场景下，经交叉验证筛选的模型调谐参数的中位数、第一及第三四分位数。涉及的模型包括岭回归（Ridge）、最小绝对收缩和选择算子（least absolute shrinkage and selection operator, LASSO）、弹性网L1-L2（Enet 1）、弹性网L2-L1（Enet 2）以及弹性网L1+L2（Enet 3）。本数据集同时呈现了不同场景与样本量下收缩参数的分布情况。
