Mixture and latent class models are identified only up to a permutation of the latent classes, the label-switching indeterminacy. This function reports the latent categorical random vertices whose value permutation leaves the diagram invariant, making the indeterminacy a visible property of the specification.
Value
A character vector of latent categorical random vertex names (empty if the model has no mixture component).
Examples
umg_labelswitching(umg_mixture(umg_growth(4), c("I", "S")))
#> [1] "c"
