Implements the De Vos et al. (2024) rank condition classifier for CCE estimators. Tests whether the rank condition holds (RC=1) which ensures CCE consistency.
rank_condition(object, criterion = c("er", "gr"))An object of class dcce_rank with elements m (number of
common factors), g (rank of average factor loadings), RC (1 if
rank condition holds, 0 otherwise).
A dcce_fit object.
Character: "er" or "gr" for factor number selection.
Default "er".
Note: Only valid for static panels. Emits a warning if called on dynamic or PMG models.
