- •
A Bayesian network is described to help address questions regarding the cellular source of DNA from differential extractions.
- •
Sperm and epithelial scoring from microscopy and DNA profiling results are considered within the Bayesian Network.
- •
Sensitivity analysis shows that in many instances it is possible to provide strong levels of support to an individual having donating sperm (or not) to a trace.
- •
Further experimental work is suggested that will assist in assigning probabilities to nodes within the network, or to refine the network structure.
