Approximations to Finite Sample Moments of Estimators Whose Exact Sampling Distributions are Unknown
精确抽样分布未知时估计量有限样本矩的近似
The exact sampling distributions of estimators of structural parameters of econometric models are unknown except for a few simple cases. In this situation two alternative approaches towards evaluating finite sample properties of various estimators have been adopted in the literature: (i) Monte Carlo experiments, and (ii) the approach pioneered by Nagar and his students in which the sampling error of an estimator is expressed as the sum of an infinite series of random…
