Reverse Survival Fertility Estimation Function

Description

Reverse Survival Fertility Estimation

Usage

FertRevSurv(
  ages1_c = 0:14,
  popx1_c,
  ages5_w = seq(10, 65, 5),
  popx5_w,
  lx1_c,
  lx5_w,
  asfr = c(0, 0.017, 0.055, 0.057, 0.041, 0.022, 0.007, 0.002),
  asfr_15prior = NULL,
  q0_5 = NULL,
  q15_45f = NULL,
  date_ref
)

Arguments

ages1_c	children single ages vector (default 0:14)
popx1_c	children population in single ages (x1) matching ages1_c vector
ages5_w	women five-year age group ages vector ( default seq( 10, 65, 5 ) )
popx5_w	women population in five-year age group format (x5) matching ages_w vector
lx1_c	children survival function vector in single age groups from 0 to 15
lx5_w	women survival function vector in five-year age groups matching ages_w vector
asfr	age specific fertility rates for five-year age groups from 10-45 for current period of estimation
asfr_15prior	standardized age specific fertility rates for five-year age groups from 10-45 for the period of 15 years before the current inquiry period
q0_5	3 element vector for mortality probability between ages 0-4 for the period of estimation, period 5 years prior to estimation period, and period 10 years prior to estimation period
q15_45f	female adult mortality probability for the period of estimation, period 5 years prior to estimation period, and period 10 years prior to estimation period
date_ref	reference date of inquiry given in the following formats: Y-m-d (4 digit year - 2 digit month - 2 digit day), Y-m (4 digit year - 2 digit month), Y (4 digit year)

Value

data.frame with 3 elements: 'year' - reference period of fertility estimation in decimal format; 'TFR' - estimated total fertility rate; 'births' - estimated total number of births
