## S3 method for class 'GLMM_MCMC':
fitted(object, x, z,
  statistic=c("median", "mean", "Q1", "Q3", "2.5\%", "97.5\%"),
  overall=FALSE, ...)GLMM_MCMC.TRUE, fitted profiles based on posterior
    mean/median/Q1/Q3/2.5%/97.5% of the model parameters are computed.
    
    If FALSE, fitted profiles based on posterior means
    given mixture component are calculated. Nx and z
  matrices. If overall is FALSE, these are then matrices
  with one column for each mixture component.GLMM_MCMC.
