incidence_rates: Compute crude incidence rates

Description

Compute crude incidence rates

Usage

incidence_rates(ncan, py, ncan.min = 5)

Value

a 3 column data.frame containing the crude incidence rate estimate (est) and associated 95% CI (lci, uci)

Arguments

ncan

integer, number of cancer

py

integer, number of person-year

ncan.min

integer, minimum number of observation required not to mask the CI's out

Crude incidence rates and associated 95% confidence interval are computing assuming a Poisson distribution and the exact method.
