Conformal Bayesian network (CBN) using different combinations of spoligotypes and MIRUs. In (a) only spoligotypes and 12 loci of MIRU (MIRU1 + M
) are observed. The components of the network corresponding to the 12 loci of MIRU in MIRU2 are ignored as shown by the dotted lines. (b) CBN predicts using spoligotype only, treating M
as a missing variable and ignoring all other MIRU portions of the network. The shaded nodes refer to hidden values in each case, and the nodes represented with dotted outlines are not used for prediction.
