| bf {BDgraph} | R Documentation |
Compute the Bayes factor between the structure of two graphs.
bf( num, den, bdgraph.obj, log = TRUE )
num,
den |
An adjacency matrix corresponding to the true graph structure in which a_{ij}=1 if there is a link between notes i and j, otherwise a_{ij}=0.
It can be an object with |
bdgraph.obj |
An object of |
log |
A character value. If TRUE the Bayes factor is given as log(BF). |
A single numeric value, the Bayes factor of the two graph structures num and den.
