随机优化的估计和推断:三个例子

Estimation and Inference by Stochastic Optimization: Three Examples

Jean-Jacques Forneron, Serena Ng

摘要:

本文阐述了Forneron & Ng(2020)中设计的两种算法:重采样牛顿-拉夫森(rNR)和重采样拟牛顿(rqN)算法,它们可以加快结构模型的估计和自举推理。对BLP的经验应用表明,计算时间从标准引导的近5小时减少到rNR的1小时多一点,而使用rqN仅需15分钟。第一次蒙特卡洛演习说明了在概率单位IV回归估计和推断的方法的准确性。第二个练习还说明了统计效率增益相对于标准估计的模拟为基础的估计使用动态面板回归的例子。

英文摘要:

This paper illustrates two algorithms designed in Forneron & Ng (2020): the resampled Newton-Raphson (rNR) and resampled quasi-Newton (rqN) algorithms which speed-up estimation and bootstrap inference for structural models. An empirical application to BLP shows that computation time decreases from nearly 5 hours with the standard bootstrap to just over 1 hour with rNR, and only 15 minutes using rqN. A first Monte-Carlo exercise illustrates the accuracy of the method for estimation and inference in a probit IV regression. A second exercise additionally illustrates statistical efficiency gains relative to standard estimation for simulation-based estimation using a dynamic panel regression example.
