disputed Bayesian Networks
Description
A template Bayesian network for combining forensic evidence on an item with an uncertain relation to the disputed activities.
Format
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 10). The probabilities were given in the referenced paper. The vertices are:
- BGFibersYtop
Backgroun fibers present on Y top (false, true);
- BGM
Background fibers matching sweater present on Y top (false, true);
- BGMnotM
Background fibers not matching sweater present on Y top (false, true);
- BGYonS
Background of fibers matching Y top on sweater (false, true);
- CaseFind
Case findings on sweater (false, true);
- DNAfind
DNA findings on sweater (DNA X, DNA U, DNA X + U, No DNA);
- DNAX
DNA X present on sweater (false, true);
- FiberfindSweater
Fiber findings on Sweater (false, true);
- FiberfindYtop
Fiber findings on Y top (matching, not matching, both matching and not matching, no fibers);
- FibersMSonY
Fibers matching sweater on Y top (false, true);
- FibersnotMSonY
Fibers not matching sweater on Y top (false, true);
- FibersYonS
Fibers matching Y top on Sweater (false, true);
- Prop
Who strangled person Y? (H1, H2);
- Sweater
Sweater worn by Mr. X during incident (false, true);
- TPRaltactX
Transfer of DNA X from X to sweater via X wearing sweater two weekd before incident (false, true);
- TPRStoYtop
Transfer of fibers from sweater to Y top during incident (false, true);
- TPRUtoYtop
Transfer of fibers from unknown garment to Y top during incident (false, true);
- TPRXstrangledY
Transfer of DNA X from X to sweater via X strangling Y (false, true);
- TPRYtoptoS
Transfer of fibers from Y top to sweater during incident (false, true);
- Unkown
Unknown garment worn by offender during incident (false, true);
- WhichGarment
Which garment was worn by offender during incident? (sweater, unknown garment);
- Xaltact
X wore sweater two weeks before incident (false, true);
- XstrangledY
Mr. X strangled person Y (false, true);
Value
