check_heaping_bachi: calculate Bachi's index of age heaping

In timriffe/DemoTools: Standardize, Evaluate, and Adjust Demographic Data

calculate Bachi's index of age heaping

Description

Bachi's index involves applying the Whipple method repeatedly to determine the extent of preference for each final digit. Similarly to Myers', it equals the sum of the positive deviations from 10 percent. It has a theoretical range from 0 to 90, and 10 is the expected value for each digit. There are two implementations.

Usage

check_heaping_bachi(
  Value,
  Age,
  ageMin = 23,
  ageMax = NULL,
  method = "orig",
  details = FALSE,
  OAG = TRUE
)

Arguments

Value	numeric. A vector of demographic counts by single age.
Age	numeric. A vector of ages corresponding to the lower integer bound of the counts.
ageMin	the minimum age used for estimation, default 23
ageMax	the maximum age used for estimation, default 77
method	either "orig" or "pasex"
details	logical. Should a list of output be given
OAG	logical. Is the highest age group open?

Details

ageMax is an inclusive upper bound, treated as interval. If you want ages 23 to 77, then give ageMin = 23 and ageMax = 77. The ageMin is respected strictly, whereas ageMax is calculated flexibly- if you specify something too high then it is reduced and we warn accordingly, and if it's missing then we pick something reasonable. You can see the age ranges actually used by specifying details = TRUE.

Value

The value of the index.

Examples

 check_heaping_bachi(pop1m_pasex, Age = 0:99, 
 ageMin = 23, ageMax = 77, method = "orig", OAG =FALSE)
 check_heaping_bachi(pop1m_ind, Age = 0:100, 
 ageMin = 23, ageMax = 77, method = "orig")
 # default simpler
 check_heaping_bachi(pop1m_pasex, Age = 0:99, 
 ageMin = 23, ageMax = 77, method = "pasex", OAG = FALSE)
# linear population, should give 0 for pasex
 check_heaping_bachi(seq(100000,1000,by=-1000),Age = 0:99, 
 ageMin = 23, ageMax = 77, method = "pasex", OAG = FALSE)
# fully concentrated, should give 90 
 pop_concetrated <- rep(c(100,rep(0,9)),10)
 check_heaping_bachi(pop_concetrated, Age = 0:99, 
 ageMin = 23, ageMax = 77, method = "pasex")
 check_heaping_bachi(pop_concetrated, Age = 0:99, 
 ageMin = 23, ageMax = 77, method = "orig")
