New SWGDAM Recommendations on Communicating Likelihood Ratios

Event Dates
Event Duration
2 hours

SWGDAM recently issued recommendations on genotyping results reported as likelihood ratios, designed to promote consistency among laboratories. Members of the committee will discuss the recommendations and their foundations.

As the U.S. is transitioning toward probabilistic genotyping as a means of interpreting forensic DNA typing results and assigning statistical weight, the Scientific Working Group on DNA Analysis Methods (SWGDAM) has published recommendations on the reporting of likelihood ratios (LRs). In this webinar, members of the SWGDAM working group will introduce the recommendations and impart the historical perspective, reasoning, and empirical data considered in their development.
