Whipple's index {dhsage}

Whipple's index calculation for reproductive-age females

Description

The function provides the Whipple's index of females 15 to 49 years old who are in reproductive age with data quality.

Usage

heaping(x, a, b)

Arguments

x

a data vector of females, aged 15 to 49 year.

a

Choose the starting age for the calculation of Whipple's index.

b

Choose the ending age for the calculation of Whipple's index.

Details

Whipple's indes can be computed by the following formula

WI=\left(\frac{P_{25}+P_{30}+P_{35}+\cdots\cdots+P_{60}}{P_{23}+P_{24}+P_{25}+\cdots\cdots+P_{62}}\right)\times500

where P represents the population of reported age in completed year. There are 5 categories for the index value, ranging from very rough to highly accurate. Data is classified as being very rough (if WI > 175), rough (125 < WI < 175), approximate (110 < WI < 125), accurate (105 < WI < 110) and highly accurate (WI < 105).

Value

heaping computes the Whipple's index with the quality of age reporting.
