fertGompPF: Gompertz PF Fertility Estimation

In josehcms/fertestr: Package for Fertility and Parity Estimation

Gompertz PF Fertility Estimation

Description

Performs Gompertz PF model for fertility estimation by user's F and P points selection

Gompertz PF Fertility Estimation

Usage

fertGompPF(
  ages = seq(15, 45, 5),
  asfr,
  P = NULL,
  level = FALSE,
  madef = "12m",
  sel.ages = c(20, 25, 30, 35, 40, 45),
  plot.diagnostic = TRUE
)

fertGompPF(
  ages = seq(15, 45, 5),
  asfr,
  P = NULL,
  level = FALSE,
  madef = "12m",
  sel.ages = c(20, 25, 30, 35, 40, 45),
  plot.diagnostic = 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))
asfr	A vector of age-specific fertility rates by five-year age group - same groups as 'ages'
P	A vector of mean parities by five-year age group - same groups as 'ages'
level	TRUE for correction of fertility level using parity data information, false for correction of fertility shape only
madef	Mother's age definition: '0m' for age at birth of child, '12m' for age at survey for 12 months data (default), '24m' for age at survey for 24 months data, '36m' for age at survey for 36 months data
sel.ages	select ages for curve fitting
plot.diagnostic	plot diagnostic graph

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
