A template Bayesian network for combining forensic evidence on an item with an uncertain relation to the disputed activities.
An object of class bn.fit. Refer to the documentation of bnlearn for details.
A discrete Bayesian network for the evaluation of transfer evidence given activity level propositions considering a dispute about the relation of an item to one or more activities (Figure 9). The probabilities were given in the referenced paper. The vertices are:
Background fibers present on Y top (false, true);
Background fibers matching sweater present on Y top (false, true);
Background fibers not matching sweater present on Y top (false, true);
Fibers matching Y top on sweater (false, true);
Background of fibers matching Y top on sweater (false, true);
Background DNA u on sweater (false, true);
Case findings on sweater (false, true);
DNA findings on sweater (DNA X, DNA U, DNA X + U, No DNA);
DNA U present on sweater (false, true);
DNA X present on sweater (false, true);
Fiber findings on Sweater (false, true);
Fiber findings on Y top (matching, not matching, both matching and not matching, no fibers);
Fibers matching sweater on Y top (false, true);
Fibers not matching sweater on Y top (false, true);
Who strangled person Y? (H1, H2);
Sweater worn by offender during incident (false, true);
Transfer of DNA X from X to sweater via X wearing sweater two weekd before incident (false, true);
Transfer of fibers from sweater to Y top during incident (false, true);
Transfer of DNA U from U to sweater via U strangling Y (false, true);
Transfer of fibers from unknown garment to Y top during incdient (false, true);
Transfer of DNA X from X to sweater via X strangling Y (false, true);
Transfer of fibers from Y top to sweater during incident (false, true);
Unknown person strangled person Y (false, true);
Unknown garment worn by offender during incident (false, true);
Which garment was worn by offender during incident? (sweater, unknown garment);
X wore sweater two weeks before incident (false, true);
Mr. X strangled person Y (false, true);
