Practical Application of the Likelihood Ratio

Sunday September 12th, 2021 // 1:00 pm - 4:00 pm // Monterrey Rooms 1-3

In-Person Registration$125.00
Virtual Registration$125.00

Fee includes materials. We encourage early registration and will be waiving cancelation penalties for 2021.

Description:

This workshop will give the audience an introduction to the assignment of the likelihood ratios (LR) for single source and mixed DNA profiles. Attendees will become familiar with the mathematical models and calculations for LRs from probabilistic genotyping software. Advanced examples including LRs for small pedigrees will be explored.  We will cover how to report LRs with emphasis on avoiding fallacies (including the transposed conditional or prosecutor’s fallacy). Worked examples will help the attendees understand the theoretical concepts.  Attendees should have a solid understanding of algebra and bring a calculator to the workshop. Handouts will be provided.

 

Learning Outcomes:

  • Calculating LRs for mixtures
  • Calculating LRs for small pedigrees
  • Verbalising the LR

 

Intended Audience:

This workshop is intended for DNA analysts, supervisors, technical leaders, attorneys and judges. A foundation in Algebra is required.
