make_structure_move: Makes a structure move.

Description

This function makes a network structure move.

Usage

make_structure_move(x, y, S, B, Sig2, q, qmax, network.info, method, Mphase, E, fixed.edges, HYPERvar)

Arguments

x
Response data.
y
Target data.
S
Network structure for the current target node, a NumSegs by NumNodes matrix.
B
Same as S, but including the regression parameters.
Sig2
Sigma squared parameters.
q
Number of nodes.
qmax
Maximum number of parents.
network.info
Network information, as collected by CollectNetworkInfo.
method
Information sharing method: Either 'poisson', 'exp_hard',

'exp_soft', 'bino_hard', 'bino_soft'.

Mphase
Segment boundary positions.
E
Changepoint vector.
fixed.edges
Matrix of size NumNodes by NumNodes, with fixed.edges[i,j]==1|0 if the edge between nodes i and j is fixed, and -1 otherwise. Defaults to NULL (no edges fixed).
HYPERvar
Hyperparameter variables.

Value

Returns a list containing the following elements:
newS
Updated network structure.
newB
Updated network structure with regression parameters.
move
Type of move being made: 1 for network structure moves.
accept
1 if the move has been accepted, 0 otherwise.
