As Davidson and MacKinnon (2004, p.532) indicate, a Hansen-Sargan test of the overidentifying restrictions is based on the 3SLS criterion function evaluated at the 3SLS point and interval parameter estimates.

Webb9 juli 2024 · Lee and Okui proposed a modification of the Sargan’s test of overidentifying restrictions in a homoscedastic framework when the number of instruments L grows with the sample size n. They established the asymptotic null distribution of their proposed test statistic and studied its local power under some regularity conditions.
