Implementation following the PASEX spreadsheet SINGAGE. Myers' measures preferences for each of the ten possible digits as a blended index. It is based on the principle that in the absence of age heaping, the aggregate population of each age ending in one of the digits 0 to 9 should represent 10 percent of the total population.

check_heaping_myers(
Value,
Age,
ageMin = 23,
ageMax = 82,
details = FALSE,
method = "orig"
)

## Arguments

Value numeric. A vector of demographic counts by single age. numeric. A vector of ages corresponding to the lower integer bound of the counts. integer. The lowest age included in calculations. Default 25. integer. The upper age bound used for calculations. Default 82. logical. Default FALSE. If TRUE, then a list is returned with some relevant parameters. either "orig" or "pasex"

## Value

The value of the index.

## Details

ageMax is an inclusive upper bound, treated as interval. If you want ages 23 to 82, then give ageMin = 23 and ageMax = 82, not 83 ageMax may be internally rounded down if necessary so that ageMax - ageMin + 1 is evenly divisible by 10. If in doubt, specify details = TRUE, and you can check which ageMax is actually used internally.
