MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -It also represents and depicts related trade-off between specificity and sensitivity since TPR is equivalent with sensitivity and FPR indicates the value of 1-specificity.

Detailed explanation-2: -Specificity refers to the test’s ability to correctly reject healthy patients without a condition. Mathematically, this can be written as: A positive result in a test with high specificity can be useful for “ruling in” disease, since the test rarely gives positive results in healthy patients.

Detailed explanation-3: -We agree that the common use of the term false-positive rate is to describe the converse of specificity (i.e., one minus specificity). In the accompanying table, we list commonly used parameters for test accuracy.

Detailed explanation-4: -Sensitivity refers to a test’s ability to designate an individual with disease as positive. A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed. The specificity of a test is its ability to designate an individual who does not have a disease as negative.
