generate8chain: generation of a /chain/ /nbn/

In rbmn: Handling Linear Gaussian Bayesian Networks

generation of a /chain/ /nbn/

Description

[randomly] generates a /chain/ /nbn/.

Usage

generate8chain(rnn=c(3, 7), proo=0.5, rcor=c(-1, 1), rmu=c(0, 0), rsig=c(0, 1),
	  nona=r.form3names(max(rnn)))

Arguments

rnn	Range of the number of nodes.
proo	Probabilit[y|ies] that the successive and acceptable nodes be colliders. Can be a vector.
rcor	Range of the correlations between neighbour nodes.
rmu	Range of the expectations.
rsig	Range of the standard deviations.
nona	Proposed names for the maximum number of nodes, only the necessary first ones will be used.

Details

Proposed ranges can be a unique value, implying no randomness in the value.
Roots are placed according to proo probabilities, then collider are placed in between with uniform probability on the possibles nodes.

Value

A /chain/ coding list is returned.

Examples

 set.seed(1234);
 print8chain(generate8chain());
 print8chain(generate8chain());
 print8chain(generate8chain(rnn=10, rcor=0.5));
 print8chain(generate8chain(rnn=10, rcor=0.5));
