The use of floating absolute risks does not alter the relative risks but slightly reduces the variances of the relative risks that are not defined as 1·0, and also reduces unwanted covariances between them. Where only two groups were … incarnation\u0027s 6wWitrynaAbstract Floating absolute risks are an alternative way of presenting relative risk estimates for poly-chotomous risk factors. Instead of choosing one level of the risk factor as a reference category, each level is assigned a “floated ” variance which describes the uncertainty in risk without reference to another level. incarnation\u0027s 70
