In this session, we review two of the most often-suggested quantitative approaches, the two-stage approach and the likelihood ratio (Bayes factor) approach. Specific topics include:<\/p>\n<ul>\n<li>The two-stage approach to assessing forensic evidence\n<ul>\n<li>The role of statistical tests in assessing the similarity of two samples<\/li>\n<li>Approaches for assessing the relevance of observed similarities<\/li>\n<\/ul>\n<\/li>\n<li>Introduction to the likelihood ratio approach\n<ul>\n<li>Definition and interpretation of the likelihood ratio\/Bayes factor<\/li>\n<li>Possible applications to different types of evidence (DNA, trace, pattern)<\/li>\n<li>Score-based likelihood ratios<\/li>\n<li>Sensitivity of the likelihood ratio to modeling choices<\/li>\n<\/ul>\n<\/li>\n<li>Results of studies comparing different ways of expressing source conclusions<\/li>\n<\/ul>\n<p><strong>Presenter:<\/strong><br \/>\nHal Stern<br \/>\nCo-Director of CSAFE<br \/>\nProvost, Executive Vice Chancellor, and Chancellor\u2019s Professor &#8211; University of California, Irvine<\/p>\n<p><strong>About the Short Course:<\/strong><br \/>\nSession four is the final session in the four-session short course, <a href=\"https:\/\/forensicstats.org\/courses\/\">Statistical Thinking for Forensic Practitioners<\/a>.

This short course will be held online in three sessions. Each session builds upon the previous one(s) and recordings will be available in the event registrants are unable to attend one or more of the live sessions. Researchers, collaborators, and members of the broader forensics and statistics communities are encouraged to attend. Short course registrants who attend all sessions will receive a certificate of completion.<\/p>\n<p><strong>Registration:<\/strong><br \/>\n<iframe src=\"https:\/\/app.smartsheet.com\/b\/form\/4f01cb2ccc714194a4b360572d209d07\" width=\"900\" height=\"600\"><\/iframe><\/p>","excerpt":"","slug":"statistical-thinking-for-forensic-practitioners-short-course-session4-fall2022","image":{"url":"https:\/\/forensicstats.org\/wp-content\/uploads\/2022\/03\/CategoryIcons_Statistics-e1648568754268.png","id":13264,"extension":"png","width":201,"height":200,"sizes":{"thumbnail":{"width":150,"height":150,"mime-type":"image\/png","url":"https:\/\/forensicstats.org\/wp-content\/uploads\/2022\/03\/CategoryIcons_Statistics-e1648568754268-150x150.png"},"image-size-150x150":{"width":150,"height":150,"mime-type":"image\/png","url":"https:\/\/forensicstats.org\/wp-content\/uploads\/2022\/03\/CategoryIcons_Statistics-e1648568754268-150x150.png"},"photo-album-thumbnail-small":{"width":150,"height":100,"mime-type":"image\/png","url":"https:\/\/forensicstats.org\/wp-content\/uploads\/2022\/03\/CategoryIcons_Statistics-e1648568754268-150x100.png"},"blog-carousel":{"width":201,"height":180,"mime-type":"image\/png","url":"https:\/\/forensicstats.org\/wp-content\/uploads\/2022\/03\/CategoryIcons_Statistics-e1648568754268-201x180.png"},"blog-showcase":{"width":201,"height":180,"mime-type":"image\/png","url":"https:\/\/forensicstats.org\/wp-content\/uploads\/2022\/03\/CategoryIcons_Statistics-e1648568754268-201x180.png"},"portfolio-four_x_x-@mobile":{"width":201,"height":184,"mime-type":"image\/png","url":"https:\/\/forensicstats.org\/wp-content\/uploads\/2022\/03\/CategoryIcons_Statistics-e1648568754268-201x184.png"}}},"all_day":false,"start_date":"2022-11-04 10:00:00","start_date_details":{"year":"2022","month":"11","day":"04","hour":"10","minutes":"00","seconds":"00"},"end_date":"2022-11-04 12:00:00","end_date_details":{"year":"2022","month":"11","day":"04","hour":"12","minutes":"00","seconds":"00"},"utc_start_date":"2022-11-04 15:00:00","utc_start_date_details":{"year":"2022","month":"11","day":"04","hour":"15","minutes":"00","seconds":"00"},"utc_end_date":"2022-11-04 17:00:00","utc_end_date_details":{"year":"2022","month":"11","day":"04","hour":"17","minutes":"00","seconds":"00"},"timezone":"UTC-5","timezone_abbr":"UTC-5","cost":"","cost_details":{"currency_symbol":"","currency_code":"","currency_position":"prefix","values":[]},"website":"","show_map":true,"show_map_link":true,"hide_from_listings":false,"sticky":false,"featured":false,"categories":[{"name":"Short Course","slug":"short-course","term_group":0,"term_taxonomy_id":77,"taxonomy":"tribe_events_cat","description":"","parent":0,"count":23,"filter":"raw","id":77,"urls":{"self":"https:\/\/forensicstats.org\/wp-json\/tribe\/events\/v1\/categories\/77","collection":"https:\/\/forensicstats.org\/wp-json\/tribe\/events\/v1\/categories"}}],"tags":[{"name":"Implementation and Practice","slug":"implementation-and-practice","term_group":0,"term_taxonomy_id":87,"taxonomy":"post_tag","description":"","parent":0,"count":36,"filter":"raw","id":87,"urls":{"self":"https:\/\/forensicstats.org\/wp-json\/tribe\/events\/v1\/tags\/87","collection":"https:\/\/forensicstats.org\/wp-json\/tribe\/events\/v1\/tags"}},{"name":"Training and Education","slug":"training-and-education","term_group":0,"term_taxonomy_id":88,"taxonomy":"post_tag","description":"","parent":0,"count":28,"filter":"raw","id":88,"urls":{"self":"https:\/\/forensicstats.org\/wp-json\/tribe\/events\/v1\/tags\/88","collection":"https:\/\/forensicstats.org\/wp-json\/tribe\/events\/v1\/tags"}}],"venue":[],"organizer":[{"id":9335,"author":"62","status":"publish","date":"2021-03-24 16:01:33","date_utc":"2021-03-24 21:01:33","modified":"2021-03-24 16:01:33","modified_utc":"2021-03-24 21:01:33","url":"https:\/\/forensicstats.org\/organizer\/anthony-greiter-csafe-learning-development-specialist\/","organizer":"Anthony Greiter, CSAFE Learning &#038;
