dirtree: Create a Dirichlet-tree object

Description

dirtree is used to create a Dirichlet-tree for modelling ballots, as described by dtree_evoteid;textualelections.dtree.

Usage

dirtree(
  candidates,
  min_depth = 0,
  max_depth = length(candidates),
  a0 = 1,
  vd = FALSE
)

Value

A Dirichlet-tree representing ranked ballots, as an object of class dirichlet_tree.

Arguments

candidates

A character vector, with each element (must be unique) representing a single candidate.

min_depth

The minimum number of candidates which must be specified for a valid ballot.

max_depth

The maximum number of candidates which can be specified for a valid ballot.

a0

The prior parameter for the distribution.

vd
