We also treat the problem of selecting the best model out of a sequence of nested latent class models. In both problems, we study the asymptotic distribution of the corresponding test statistics, showing that they share the same behavior as the corresponding maximum likelihood test statistic.engbook parthttps://doi.org/10.1007/978-3-031-04137-2_20open access519.22Estadística matemática (Matemáticas)1209 Estadística
