| 摘 要： | 系统地比较了3种自助法再生样本的获取方法：经验分布函数法、改进的经验分布函数法和随机加权法。模拟结果表明，自助法再生样本最好的获取方式是改进的经验分布函数法，经验分布函数法次之，随机加权法最差。

| Abstract: | Three obtaining methods research of bootstrap regenerated samples is systematic compared. They are empirical distribution function method, improved empirical distribution function method and bayesian Joootsrtrap method. Simulation results show that improved empirical distribution function method is the best obtaining method of bootstrap regenerated samples, followed by empirical distribution function method, and bayesian bootsrtrap method is the worst. |
