Update beta -- the concentration parameter in the Dirichlet process for the individual-level latent classes. Currently, this is assumed to be the same within all group-level classes.
UpdateBeta(ba, bb, v)
Hyper-parameter a for beta.
Hyper-parameter b for beta.
Matrix of the beta-distributed variables in the stick breaking representation of the individual-level latent classes by the group-level latent classes.
Updated (posterior) value for beta based on the corresponding full conditional distribution..
