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. In this paper, a method for …

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.
WitrynaThe floating absolute risk method provides the variance of the logarithm of the hazard ratio for each category (including the reference category) to facilitate comparisons across the different exposure categories. The boxes represent hazard ratios, with the size inversely proportional to the variance of the logarithm of the hazard ratio, and ...
