WebA contingency table is just a summary of underlying data. You can convert it back from the counts shown in the contingency table to one row per observations. Consider the example confusion matrix used in the Wikipedia article with 5 true positives, 17 true negatives, 2 false positives and 3 false negatives WebThe contingency table contains the frequencies O i j of all combinations of outcomes, when there are multiple random variables that can take a finite number of values. Under the null hypothesis of independence, we can compute the expected frequencies E i j, based on the marginal sums (sums in each row).
