LAR_group: Average Estimated Lifetime Attributable Risk by Group

In LARisk: Estimation of Lifetime Attributable Risk of Cancer from Radiation Exposure

Description

LAR_group is used to estimate lifetime attributable radiation-related cancer risk by group.

Usage

LAR_group(
  data,
  pid,
  group,
  basedata,
  sim = 300,
  seed = 99,
  current = as.numeric(substr(Sys.Date(), 1, 4)),
  ci = 0.9,
  weight = NULL,
  DDREF = TRUE,
  basepy = 1e+05
)

Arguments

data	data frame containing demographic information and exposure information. See 'Details'.
pid	a vector which distinguish each person.
group	a vector or list of vectors which distinguish each group.
basedata	a list of the data of lifetime table and incidence rate table. The first element is lifetime table and the second is incidence rate table.
sim	number of iteration of simulation.
seed	a random seed number.
current	a current year. default is year of the system time.
ci	confidence level of the confidence interval.
weight	a list containing the value between 0 and 1 which is a weight on ERR model. See 'Details'.
DDREF	logical. Whether to apply the dose and dose-rate effectiveness factor.
basepy	number of base person-years

Value

LAR_group returns an object of multiple classes "LAR_group", "LAR". An object of class LAR_group is a list of LAR class objects which names of elements are group of each groups.

Examples

## example with lifetime and incidence rate table in 2010 Korea.
lar1 <- LAR_group(nuclear, pid=nuclear$ID, group=nuclear$distance,
                 basedata = list(life2010, incid2010))
summary(lar1)

lar2 <- LAR_group(nuclear, pid=nuclear$ID, group=list(nuclear$sex, nuclear$distance),
                 basedata = list(life2010, incid2010))
summary(lar2)
