WebDec 29, 2024 · Among the 100 patients with syphilis, 95 of them tested positive, and 5 tested negative. Among the 900 patients without syphilis, 90 tested positive, and 810 tested negative. In this case, TP=95, FN=5, FP=90, and TN=810. 6. To calculate the sensitivity, divide TP by (TP+FN). In the case above, that would be 95/ (95+5)= 95%. WebFeb 4, 2011 · Assumption: the max value in the array with size N is should be smaller than (N+1) * Integer.MAX_VALUE. We need this assumption since we well change some positive values in the array. In the first scan, find # of negative and positive values, and the max. In the second scan we create the negative section of array as follows:
