SENSPEC: Stata module to compute sensitivity and specificity results saved in generated variables
senspec inputs a reference variable with two values and a quantitative classification variable. It creates, as output, a set of new variables, containing, in each observation, the numbers and/or rates of true positives, true negatives, false positives and false negatives observed if the classification variable is used to define a diagnostic test, with a threshold equal to the value of the classification variable for that observation. The reference variable indicates the true state of the observation, such as diseased and non-diseased, or normal and abnormal. The rating or outcome of the diagnostic test is recorded in the classification variable. senspec is similar to roctab, but produces output variables instead of plots and listings, so that users can create plots and listings in their own chosen formats.
