Dirichlet sampling with structural zeros

Usage

synthetic.sampling.dirichlet.zeros(
  concentration,
  zero.fraction,
  zero.parts,
  zero.row.policy = c("first", "random"),
  count.rounding = "round",
  algorithm = "normalized.gamma.v1"
)

Arguments

concentration: Scalar or part-wise Dirichlet concentration.
zero.fraction: Fraction of rows receiving structural zeros.
zero.parts: Part indices set to zero.
zero.row.policy: Row-selection policy.
count.rounding: Count rule.
algorithm: Versioned draw algorithm.

Value

A synthetic sampling component.

Examples

  concentration = rep(1, 3), zero.fraction = 0.2, zero.parts = 1L
