Relative improvement over chance (RIOC) and phi as measures of predictive efficiency and strength of association in 2×2 tables
In a 2×2 table, phi measures the strength of the relationship and relative improvement over chance (RIOC) measures the predictive efficiency. A simplified formula for RIOC is derived. From the linkage between RIOC and the adjusted standardized residual, the variance of RIOC is calculated, thereby al...
