GEM = generalized exponential model.
1 For a key to modeling abbreviations, see Chapter 7, Exhibit 7.1.
2 Unequal weighting effect (UWE) defined as 1 + [(n - 1)/n]*CV 2 , where CV = coefficient of variation of weights.
3 Number of proposed covariates on top line and number finalized after modeling.
4 Nominal bounds are used in defining maximum/minimum values for the GEM adjustment factors. The realized bound is the actual adjustment produced by the modeling. The
first set of bounds listed is for high extreme values, the second for nonextreme, and the third for low extreme values.
