This paper provides a first order asymptotic theory for generalized method of moments (GMM) estimators when the number of moment conditions is allowed to increase with the sample size and the moment conditions may be weak. Examples in which these asymptotics are relevant include instrumental variable (IV) estimation with many (possibly weak or uninformed) instruments and some panel data models that cover moderate time spans and have correspondingly large numbers of instruments. Under certain regularity conditions, the GMM estimators are shown to converge in probability but not necessarily to the true parameter, and conditions for consistent GMM estimation are given. A general framework for the GMM limit distribution theory is developed based on epiconvergence methods. Some illustrations are provided, including consistent GMM estimation of a panel model with time varying individual effects, consistent limited information maximum likelihood estimation as a continuously updated GMM estimator, and consistent IV structural estimation using large numbers of weak or irrelevant instruments. Some simulations are reported. 相似文献

数量意义属逻辑、语言学范畴,是客观事物在人们头脑中的反映,是经过人们概括、抽象而产生的某一类事物在数量上的共同特征。从俄汉对比角度研究数量意义中的一种——大约数量意义,目的在于揭示其相异和相同之处。本文遵循从意义到形式,从俄语到汉语的原则,通过大量的例证,对比俄汉语大约数量意义的表达手段,揭示俄汉语大约数量结构构成规律和语义差别,解决俄汉语教学中学生在翻译此类问题时的模糊认识,具有较强的实践价值。 相似文献

Rank correlations are shown to be generally robust in the sense that the tests for independence, which they naturally define, have weakly equicontinuous error probabilities. The ordinary sample correlation coefficient is not robust in this respect. 相似文献

In this paper different pairs of urns are considered. We are interested in the number of ways in which N balls can be placed into the urns so that differences and ratios between the number of balls in certain pairs of urns are the same. 相似文献

In this note, we obtain, based on the sample sum, a statistic to test the homogeneity of a random sample from a positive (zero truncated) Lagrangian Poisson distribution given in Consul and Jain (1973). This test statistic conforms, in a special case, to Singh (1978). A goodness-of-fit test statistic for the Borel-Tanner distribution is obtained as a particular case cf our results. 相似文献

The paper develops a general framework for the formulation of generic uniform laws of large numbers. In particular, we introduce a basic generic uniform law of large numbers that contains recent uniform laws of large numbers by Andrews [2] and Hoadley [9] as special cases. We also develop a truncation approach that makes it possible to obtain uniform laws of large numbers for the functions under consideration from uniform laws of large numbers for truncated versions of those functions. The point of the truncation approach is that uniform laws of large numbers for the truncated versions are typically easier to obtain. By combining the basic uniform law of large numbers and the truncation approach we also derive generalizations of recent uniform laws of large numbers introduced in Pötscher and Prucha [15, 16]. 相似文献

The connection between Stirling numbers of the first kind and records is well-known. Applying this relationship, we derive
bounds for the maximum likelihood estimator of the sample size based on the number of observed records. The proof proceeds
by a remarkable expression of the mode of the unsigned Stirling numbers of the the first kind due to Hammersley. Moreover,
this representation of the mode leads to an accurate approximation of the maximum likelihood estimator. 相似文献
