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 for details.
