摘要我们提出了一种惩罚似然方法,它同时适用于多项Logistic回归模型,并结合了响应类别的子集。当优化变量中的列对相等时,惩罚是不可微的。这鼓励在估计器中的这些列成对相等,这对应于响应类别组合。我们使用交替方向乘子法算法来计算估计量,并讨论了算法的收敛。文中还讨论了预测和模型选择问题。本文的补充材料可以在网上找到。
Abstract We propose a penalized likelihood method that simultaneously fits the multinomial logistic regression model and combines subsets of the response categories. The penalty is nondifferentiable when pairs of columns in the optimization variable are equal. This encourages pairwise equality of these columns in the estimator, which corresponds to response category combination. We use an alternating direction method of multipliers algorithm to compute the estimator and we discuss the algorithm’s convergence. Prediction and model selection are also addressed. Supplemental materials for this article are available online.
