WebThe importance of controlling for intragroup correlation in clustered samples is largely acknowledged in applied econometrics. However, this issue has remained underexplored in tourism research . In many instances, the observation units are naturally grouped, either geographically or due to the sampling scheme, and therefore the iid assumption ... Web14 oct. 2024 · We study two cluster-robust variance estimators (CRVEs) for regression models with clustering in two dimensions and give conditions under which t -statistics based on each of them yield asymptotically valid inferences. In particular, one of the CRVEs requires stronger assumptions about the nature of the intra-cluster correlations.
