## S3 method for class 'RprobitB_fit'
summary(object, FUN = c(mean = mean, sd = stats::sd, `R^` = R_hat), ...)

Arguments

• data: An object of class RprobitB_data.

• scale: A character which determines the utility scale. It is of the form <parameter> := <value>, where <parameter> is either the name of a fixed effect or Sigma_<j>,<j> for the <j>th diagonal element of Sigma, and <value> is the value of the fixed parameter.

• normalization: An object of class RprobitB_normalization.

• R: The number of iterations of the Gibbs sampler.

• B: The length of the burn-in period, i.e. a non-negative number of samples to be discarded.

• Q: The thinning factor for the Gibbs samples, i.e. only every Qth sample is kept.

• latent_classes: Either NULL (for no latent classes) or a list of parameters specifying the number of latent classes and their updating scheme:

  • C: The fixed number (greater or equal 1) of latent classes, which is set to 1 per default. If either weight_update = TRUE

    or dp_update = TRUE (i.e. if classes are updated), C

    equals the initial number of latent classes.

  • weight_update: A boolean, set to TRUE to weight-based update the latent classes. See ... for details.

  • dp_update: A boolean, set to TRUE to update the latent classes based on a Dirichlet process. See ... for details.

  • Cmax: The maximum number of latent classes.

  • buffer: The number of iterations to wait before a next weight-based update of the latent classes.

  • epsmin: The threshold weight (between 0 and 1) for removing a latent class in the weight-based updating scheme.

  • epsmax: The threshold weight (between 0 and 1) for splitting a latent class in the weight-based updating scheme.

  • distmin: The (non-negative) threshold in class mean difference for joining two latent classes in the weight-based updating scheme.

• prior: A named list of parameters for the prior distributions. See the documentation of check_prior for details about which parameters can be specified.

• gibbs_samples: An object of class RprobitB_gibbs_samples.

• class_sequence: The sequence of class numbers during Gibbs sampling of length R.

• comp_time: The time spent for Gibbs sampling.

• ...: Currently not used.

Returns

An object of class RprobitB_fit.
