A response to Busey & Klutzke (2022): Regarding subjective assignment of likelihood ratios

Research output: Contribution to journalLetter, comment/opinion or interview


Busey & Klutzke (2022) states that “Morrison (2012) has argued that the likelihood ratio need not be quantitative but could be based on the expert's subjective evaluation.” The statement appears to suggest that Morrison (2012) argued in favour of subjective assignment of likelihood-ratio values. This interpretation of Morrison (2012) is incorrect.
