At 1:57, the false positive rate should be 2/5. If you are declaring diseased to be positive class, then showing healthy people as diseased is false positive. Am I correct?

Thank you for the video. I wondering how to get the 45 for the threshold value which is positive or negative

It would be "An" ROC curve because we pronounce the R as "ar". So that's a bit annoying since you say a ROC curve for the entire video xd. But this was a nice explanation thanks.

Very Clear Explanation . Can you explain RoC for defaulter/ non defaulter ( altaman z score) and relate it to Type 1 error and type 2 error

Why is the false positive rate 3/5 and not 2/5 when 2 are wrongly classified as sick?

i think theres a mistake in this video at 2:44 where "true negatives" means diseased persons correctly classified as diseased

False positive rate should be 2/5.. not 3/5 at 2.00 minutes of the video.. 3/5 is true negative rate
