Cragg-donald statistic
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 ... WebApr 14, 2024 · The test results also suggest that both the Cragg–Donald Wald F statistic and the Kleibergen–Paap rk Wald F statistic exceed the critical value of the Stock–Yogo weak identification F test. These results prove that our instrumental variables adopted in this paper are appropriate. 5. Mechanism Test

WebThe critical values of the Cragg-Donald test statistic reject the null hypothesis that the endogenous regressor (credit access) is weakly identified. The Kleibergen-Paap test also rejects the hypothesis of under-identification, that is, the minimal canonical correlation between the endogenous variable and the instruments is statistically ...

WebThe degrees of freedom adjustment for the rk statistic is (N-L)/L1, as with the Cragg-Donald F statistic, except in the cluster-robust case, when the adjustment is N/(N-1) * (N_clust-1)/N_clust, following the standard Stata small-sample adjustment for cluster-robust. In the case of two-way clustering, N_clust is the minimum of N_clust1 and N ...
