fluids Bayesian Networks
Description
Use of Bayesian Networks for the investigation of the nature of biological material in casework.
Format
A discrete Bayesian network to assess the presence of sperm in the recovered material and combine potentially contradictory observations. The network was available from an associated repository. The vertices are:
- Concentration_EPI
Total concentration of male DNA in non sperm fraction (0-0.0002, 0.0002-0.0005, 0.0005-0.001, 0.001-0.002, 0.002-0.004, 0.004-0.01, 0.01-0.01, 0.02-inf);
- Sperm
(Yes, No);
- Nature_of_stain
(At least Sperm, Lubricant/urine/vaginal secretion);
- Location
(Vaginal/condom/panties, Other);
- Concentration_Total
Total concentration of male DNA (0-0.0002, 0.0002-0.0005, 0.0005-0.001, 0.001-0.002, 0.002-0.004, 0.004-0.01, 0.01-0.01, 0.02-inf);
- AZO
(Azoospermic, Non azoospermic);
- CT
Spermatozoa detection (Positive, Negative, 1 spz, Possible spz);
- PSA
Seminal fluid test (Positive, Negative, Weak positive);
- Concentration_SP
Total concentration of male DNA in sperm fraction (0-0.0002, 0.0002-0.0005, 0.0005-0.001, 0.001-0.002, 0.002-0.004, 0.004-0.01, 0.01-0.01, 0.02-inf);
Value
An object of class bn.fit
. Refer to the documentation of bnlearn
