Using the digit-specific modified Whipple's index, this index summarizes all age preference and avoidance effects by taking the sum of the absolute differences between digit-specific Whipple's index and 1 (counting all differences as positive).
check_heaping_spoorenberg(Value, Age, ageMin = 20, ageMax = 64)
| 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 | integer. The lowest age included in calculations. Default 25. |
| ageMax | integer. The upper age bound used for calculations. Default 65. |
The value of the index.
ageMin and ageMax are applied to numerator ages, not denominators. Denominators are always 5-year age groups centered on the digit in question, and these therefore stretch into ages a bit higher or lower than the numerator ages. ageMax is an inclusive upper bound, treated as interval. If you want ages 20 to 64, then give ageMin = 20 and ageMax = 64, not 65.
