Brass PF Fertility Estimation using Coale-Trussel coefficients

Description

Brass PF Fertility Estimation using Coale-Trussel coefficients

Usage

fertBrassPF.cltrss(
  ages = seq(15, 45, 5),
  P,
  asfr,
  adjust_group = c(20),
  age_shift = TRUE
)

Arguments

ages

A vector of starting ages of five-year age groups ranging from 15 to 45 (default = c(15,20,25,30,35,40,45))

P

A vector of mean parities by five-year age group - same groups as 'ages'

asfr

A vector of age-specific fertility rates by five-year age group - same groups as 'ages'

adjust_group

A vector of age-groups from 'ages' to be used for selection of PF ratios to adjust asfr data (default set to 20 (20-24 five-year age group))

age_shift

TRUE (default) if fertility rates are calculated from births in a 12-month period by age of mothed at the end of period and FALSE if fertility rates are calculated from births by age of mother at the end of the period

Value

A list with 3 elements: pf_data data frame with columns ages, P for mean parities, asfr, Fi for cumulate fertility estimated from Brass coefficients,PF for ratios P/F and adj_asfr for adjusted asfr; tfr_unadj for unadjusted total fertility rate estimate; and tfr_adj for adjusted total fertility rate estimate by applying the selected age-group PF ratio

Examples

## Bangladesh 1974 survey data:
ages_bd = c(15, 20, 25, 30, 35, 40, 45)
asfr_bd = c(0.1063, 0.2296, 0.2154, 0.1825, 0.1339, 0.0644, 0.0336)
P_bd    = c(0.385, 1.847, 3.485, 4.917, 5.861, 6.194, 6.084)
fertBrassPF.cltrss(P = P_bd, asfr = asfr_bd, adjust_group = c(20,25,30))
