The<unk>  (RII) is a regression-based<unk>  which summarizes the magnitude of socio-economic status (SES) as a source of<unk> es in health. RII is useful because it takes into account the size of the population and the<unk>  disadvantage experienced by different groups. The disease outcome is regressed on the proportion of the population that has a higher position in the hierarchy. The RII is particularly valuable when comparing risk factors <unk> endent variables) that are on very different scales (e.g. low SES, low IQ, cigarette smoking). The RII is calculated in the following way: # Rank cases on each of the variables # For tied ranks and for categorical variables, assign the mean rank # Divide the ranks by the sample size, creating a value ranging from 0 to 1
