Ans. is `d' i.e., None of the above False positive rate = 1-specificity or Specificity = 1-false positive rate False negative rate -- 1-sensitivity or Sensitivity = 1-false negative rate Post test probability = Pretest probability Likelihood ratio o Predictive value depends upon prevalance.
Sensitivity is 1 - False positive rate
Sensitivity is 1 - False negative rate
Post-test probability is pre-test probability multiplied by prevalence
None of the above
