Directly age-standardised rate — Agestd • rmorie

Formula: ASR = sum_i w_i r_i / sum_i w_i; var(ASR) = sum_i w_i^2 r_i / n_i / (sum_i w_i)^2

Usage

Agestd(rates, standard_pop, person_time = NULL)

Arguments

rates: See Usage.
standard_pop: See Usage.
person_time: See Usage.

Value

List with asr, variance, se, ci_lower, ci_upper, weights, k.
