I have a report that uses age AND SEX adjusted rates. What is this, and why doesn NM-IBIS produce age and sex adjusted rates?
It is sometimes appropriate to adjust by other variables besides age. Rates that have been adjusted by age and sex use age- and sex-specific rates, weighted by twice the number of weights (one set for males and one set for females), but the total of all the weights still must sum to 1.0. IBIS-Q doesn’t compute these rates because there is little demand for it.
