expected | R Documentation |

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 |
