Convergence of Luo and Tsai's iterative algorithm for estimation in proportional likelihood ratio models
比例似然比模型中 Luo 与 Tsai 估计迭代算法的收敛性
Luo & Tsai (2012, Biometrika) introduced the proportional likelihood ratio model. They proposed an iterative algorithm for the estimation of the baseline distribution function but did not establish its convergence. Here we provide a proof of convergence.
