Calculation of likelihood ratios in forensic glass comparisons; introduction to a R code and Shiny app applied to existing background glass elemental databases

December 13, 2021
Anuradha Akmeemana, Ruthmara Corzo, Jodi Webb, Emily Haase, Jose Almirall
The use of standardized and robust analytical methods for the quantitative analysis of the elemental composition of glass fragments enables the characterization and comparison of glass as forensic evidence. This paper in- troduces a new R-based Shiny
