Webto find the incidence of the outcome of interest (e.g. disease, death, or change in health). Two measures of incidence are risks and rates. Risks and rates can be further manipulated to provide additional information on the effects of the exposure of interest, such as risk ratios, rate ratios, attributable risks (risk or rate differences) WebFor example, the AGE=1, CAR=SMALL population is identified in the model by β 0 + β 3 + β 4, that is the intercept plus the third (small) CAR parameter plus the first (1) AGE parameter.
