S3 Method for Computation of Marginal Posterior Distribution — IRT.marginal_posterior • CDM

Computes marginal posterior distributions for fitted models in the CDM package.

IRT.marginal_posterior(object, dim, remove_zeroprobs=TRUE, ...)

# S3 method for din
IRT.marginal_posterior(object, dim, remove_zeroprobs=TRUE, ...)
# S3 method for gdina
IRT.marginal_posterior(object, dim, remove_zeroprobs=TRUE, ...)
# S3 method for mcdina
IRT.marginal_posterior(object, dim, remove_zeroprobs=TRUE, ...)

Arguments

object: Object of class din, gdina, mcdina
dim: Numeric or character vector indicating dimensions of posterior distribution which should be marginalized
remove_zeroprobs: Logical indicating whether classes with zero probabilities should be removed
...: Further arguments to be passed

Value

List with entries

marg_post: Marginal posterior distribution
map: MAP estimate (individual classification)
theta: Skill classes
