Calculate IRS Coverage from DHS Data

Estimates Indoor Residual Spraying (IRS) coverage at the household level using survey-weighted methods from DHS Household Records data.

Usage

calc_irs_dhs_core(
  dhs_hr,
  survey_vars = list(cluster = "hv021", weight = "hv005", stratum = "hv022", irs =
    "hv253"),
  region_var = NULL,
  gps_data = NULL,
  gps_vars = list(cluster = "DHSCLUST", lat = "LATNUM", lon = "LONGNUM"),
  shapefile = NULL,
  admin_level = NULL,
  join_nearest = TRUE
)

Arguments

dhs_hr

DHS Household Records (HR) dataset.

survey_vars

Named list mapping DHS variable names. Required keys:

• cluster: Cluster/PSU ID (default: "hv021")

• weight: Survey weight (default: "hv005")

• stratum: Stratum variable (default: "hv022")

• irs: IRS variable (default: "hv253")

region_var

Optional column name to use as grouping variable.

gps_data

Optional DHS GPS dataset.

gps_vars

Named list for GPS variables.

shapefile

Optional sf object with administrative boundaries.

admin_level

Character vector of admin columns from shapefile.

join_nearest

Logical; if TRUE, assigns clusters outside polygons to nearest admin unit.

Value

Tibble with IRS estimates including: dhs_irs, dhs_irs_low, dhs_irs_upp, dhs_n_households_irs, dhs_n_sprayed.
