Get Rates of Misleading Evidence for SLRs
Description
Calculate the rates of misleading evidence for score-based likelihood ratios (SLRs) when the ground truth is known.
Usage
get_rates_of_misleading_slrs(df, threshold = 1)
Arguments
df |
A dataframe of SLRs from |
threshold |
A number greater than zero that serves as a decision threshold. If the ground truth for two documents is that they came from the same writer and the SLR is less than the decision threshold, this is misleading evidence that incorrectly supports the defense (false negative). If the ground truth for two documents is that they came from different writers and the SLR is greater than the decision threshold, this is misleading evidence that incorrectly supports the prosecution (false positive). |
Value
A list
Examples
comparisons <- compare_writer_profiles(test, score_only = FALSE)
get_rates_of_misleading_slrs(comparisons)
