WebSep 30, 2024 · The results of the underidentification test show that the Anderson LM statistic is significant at the 1% level, indicating that the model can be identified. Additionally, the Cragg-Donald Wald F statistic is significant at the 1% level, implying that there is no weak identification of an instrumental variable. Hence, the choice of the “Bartik ... WebAug 9, 2024 · 1. When there is only one endogenous regressor, the singular value decomposition is trivial and the test seems to reduce to F or chi-square. It's just their Assumption 1 or (17) with q = 0, and there is nothing special. Apply m = 1 and q = 0 to (1) so Λ q is k × 1, where k is the number of extra instruments. – chan1142.
