Calculate ANC Coverage from DHS Data (standardized long-format output)

Source: R/indicator_anc.R
calc_anc_dhs.Rd

Computes ANC 1+/2+/3+/4+/8+ coverage indicators nationally and optionally by subnational region, returning the standardized list(adm0, adm1) output.

Usage

calc_anc_dhs(
  dhs_ir,
  survey_vars = list(cluster = "v021", weight = "v005", stratum = "v022", interview_date
    = "v008", birth_date = "b3_01", anc_visits = "m14_1"),
  birth_window_months = 24,
  region_var = NULL,
  gps_data = NULL,
  gps_vars = list(cluster = "DHSCLUST", lat = "LATNUM", lon = "LONGNUM"),
  shapefile = NULL,
  admin_level = NULL,
  join_nearest = TRUE,
  ci_method = "logit"
)
