sampleK_e0

This sampling step only relies on the current
partition and is independent of the current component-specific
parameters, see Frühwirth-Schnatter et al (2021).

internal

Fits Bayesian finite mixtures with an unknown number of components using the telescoping sampler and different component distributions. For more details see Frühwirth-Schnatter et al. (2021) <doi:10.1214/21-BA1294>.
