onestepgmm：可能会产生较大的估计偏差，因为其仅通过一次迭代就得出最终结果。twostepgmm：通常可以产生更准确的估计结果，因为通过两次迭代，可以更精确地调整参数估计。综上所述，onestepgmm和twostepgmm的主要区别在于它们进行迭代估计的步骤次数，这直接影响了它们的计算量和估计准确性。
1. onestepgmm和twostepgmm都是基于广义方法矩（GMM）估计的方法，用于估计参数。2. 它们在估计参数的步骤上有一些区别。onestepgmm是一种一步估计方法，它通过仅对GMM的初始估计进行一次迭代来直接获得参数估计。3. 具体来说，onestepgmm使用初始的GMM估计来计算有效的权重矩阵，并将其代入到原始的GMM估...

Hypothesis Testing with Two-Step GMM Estimators 来自 Semantic Scholar 喜欢 0 阅读量: 31 作者: Simon Gilchrist,Charles P. Himmelberg 摘要: Two-step generalized method of moment (2SGMM) estimation procedures are often applied to models that impose nonlinear cross-equation restrictions. Though less...
As shown in Using gmm to solve two-step estimation problems, this can be solved with the generalized method of moments using gmm. This continues the series of posts where we illustrate how to obtain correct standard errors and marginal effects for models with multiple steps. In the previous ...
The first order sampling properties are shown to be equivalent to efficient two-step GMM. New tests are introduced for hypothesis on the model's parameters. The higher order bias is calculated and situations of practical interest are noted where this bias will be smaller than for currently ...
