Hi Professor Campo, the numbers during 8:42 don't seem to make sense, across the rows. Since 82+1= 83, not 81. I think it was supposed to be 80TP and 12 FN to even the numbers out. Please let me know if I'm missing something. This is Diana Y.
Dear Dr. Campo, I did two different test for detection of a bacteria in the same population. Is it possible to calculate PPV, NPV, Sensitivity and Specificity of each test Separately with out gold standard ? Could you guide me please. Thank you for your consideration and confirmation would be appreciated. Sincerely, Narjes
There are statistical techniques, such as latent class analysis, that can be used when there is no gold standard. But I am not familiar enough with the technique to guide you further.
@10:16 working across the rows wouldn't the NPV be 7/17 = 41.2% rather than 7/19 = 36.8% as you have listed?
thank you. simple explanation.
Excellent explanation of the topic. Well done.
Thank you. I really understand your presentation and it make sense for me for the first time

Did the post-test probability video ever happen?
shouldn't it be 7/17 for npv?
All questions; theory and practical applications answered.
very helpful
