标题： Analyzing Non-proportional Hazards: Use of the MRH Package

摘要： 在本手稿中，我们演示了使用R语言中的MRH包对右删失生存结果的分析。MRH包实现了多分辨率风险（MRH）模型，这是一种基于波利亚树的贝叶斯半参数方法，用于灵活估计风险率和协变量效应。 该包允许在比例风险和非比例风险假设下纳入协变量，并通过“剪枝”工具在稀疏失效时期对风险率进行稳健估计。 显示英文摘要

摘要： In this manuscript we demonstrate the analysis of right-censored survival outcomes using the MRH package in R. The MRH package implements the multi-resolution hazard (MRH) model, which is a Polya-tree based, Bayesian semi-parametric method for flexible estimation of the hazard rate and covariate effects. The package allows for covariates to be included under the proportional and non-proportional hazards assumption, and for robust estimation of the hazard rate in periods of sparsely observed failures via a "pruning" tool.
