WebJul 23, 2008 · The two clustering partitions can be summarized by a 2 × 2 table with quantities a, b, c, and d, by counting the number of pairs of objects that were placed in the same cluster in both partitions ( a ), in the same cluster in one partition but in different clusters in the other partition ( b and c ), and in different clusters in both ( d ). The degree of association between the two variables can be assessed by a number of coefficients. The following subsections describe a few of them. For a more complete discussion of their uses, see the main articles linked under each subsection heading. The simplest measure of association for a 2 × 2 contingency table is the odds ratio. Given two events, A and B, the odds ratio is defined as the ratio of the odds of A in the presence of B and th…
WebDec 16, 2024 · How to Calculate a Phi Coefficient in R A Phi Coefficient (sometimes called a mean square contingency coefficient) is a measure of the association between two binary variables. For a given 2×2 table for two random variables x and y: The Phi Coefficient can be calculated as: Φ = (AD-BC) / √(A+B) (C+D) (A+C) (B+D)
