random_parentslist {stagedtrees}

Generate a random parentslist object (DAG)

Description

generate a random DAG coded as parentslist object.

Usage

random_parentslist(n, k = 2, maxp = n)

Arguments

n

number of variables.

k

maximum number of levels for each variable.

maxp

maximum cardinality of parents sets.

Details

For each variable a subset of random cardinality (maximum maxp) of the preceding variables is randomly selected as parents set. The possible levels of each variables are randomly selected in 2,...,k.

Value

a parentslist object.

Examples

random_parentslist(5, 3, 2)

## we can generate the associated staged tree
pl <- random_parentslist(4, 2, 2)
plot(as_sevt(pl), main = as.character(pl))
