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 3). The probabilities were given in the referenced paper. The vertices are:

BGFibers

Background on fibers matching Y top on sweater (false, true);

BGU

Background DNA U 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);

DNAU

DNA U present on sweater (false, true);

DNAX

DNA X present on sweater (false, true);

FiberFind

Fiber findings on sweater(false, true);

FibersSweater

Fibers matching Y garment on sweater (false, true);

ItemProposition

Sweater worn by offender during incident (false, true);

Prop

Who strangled person Y? (H1, H2);

TPRaltactX

Transfer of DNA X from X to sweater via X wearing sweater two weekd before incident (false, true);

TPRUstrangledY

Transfer of DNA U from U to sweater via U strangling Y (false, true);

TPRXstrangledY

Transfer of DNA X from X to sweater via X strangling Y (false, true);

TPRYtoSweater

Transfer of fibers from Y top to sweater during incident (false, true);

UstrangledY

Unknown person strangled person Y (false, true);

Xaltact

X wore sweater two weeks before incident (false, true);

XstrangledY

Mr. X strangled person Y (false, true);

Value

An object of class bn.fit. Refer to the documentation of bnlearn for details.
