Sargan+Hansen：过度识别检验及Stata实现

WebbThis article surveys Denis Sargan's work on instrumental variables (IV) estimation and its connections with the general-ized method of moments (GMM). Sargan pursued his interests in IV estimation all through his career. He focused in par-ticular on asymptotic expansions of the distributions of esti-mators and test statistics.

Proof that Sargan test statistic is distributed $\\chi^2$

WebbThe Sargan statistic can also be calculated after ivreg or ivreg2 by the command overid. The features of ivreg2 that are unavailable in overid are the J statistic and the C statistic; the overid options unavailable in ivreg2 are various small-sample and pseudo-F versions of Sargan's statistic and its close relative, Basmann's statistic. http://www.ichacha.net/sargan.html WebbThe Sargan test is based on the assumption that model parameters are identified via a priori restrictions on the coefficients, and tests the validity of over-identifying restrictions. The test statistic can be computed from residuals from instrumental variables regression by constructing a quadratic form based on the cross-product of the residuals and … how do you form a society
