Compute Expected Numbers of Disease
Compute the internally indirect standardized expected numbers of disease.
expected(population, cases, n.strata)
population |
a vector of population counts for each strata in each area |
cases |
a vector of the corresponding number of cases |
n.strata |
number of strata considered |
The population and cases vectors must be balanced: all counts are sorted by area first, and then within each area the counts for all strata are listed (even if 0 count) in the same order.
expected.cases |
a vector of the expected numbers of disease for each area |
