Value

A list with the following named components:

modal_rankings

Integer matrix with the MLEs of the G component-specific consensus rankings in each row.

modal_orderings

Character matrix with the MLEs of the G component-specific consensus orderings in each row.

theta

Numeric vector of the MLEs of the G precisions.

weights
