Fitting Signal Detection Theory Models
Fitting Signal Detection Theory Models
At 2019 IAI in Reno, I presented a talk in which I described how models based on Signal Detection Theory could be used to help summarize the data from proficiency/error rate tests (where ground truth is known). The slides for that talk are found here:
As part of that talk, I created a spreadsheet that allows anyone to explore and fit Signal Detection Theory models. You can download that here:
There is a tutorial video explaining how to use the spreadsheet, which is found here:
These models can be pretty powerful, and help us understand a lot about the decisions of examiners. For more information, email me at busey@indiana.edu
