Build NBI flags from final NBI components — enemdu_build_nbi

Builds knbi, nbi, and xnbi from final NBI component variables that already exist in the data. This function does not reconstruct NBI from raw questionnaire variables.

Usage

enemdu_build_nbi_flags(
  data,
  component_vars = c("comp1", "comp2", "comp3", "comp4", "comp5"),
  nbi_count_var = "knbi",
  nbi_var = "nbi",
  extreme_nbi_var = "xnbi",
  overwrite = FALSE,
  strict_binary = TRUE
)

Arguments

data: A data frame.
component_vars: Final NBI component variables. Defaults to comp1 through comp5.
nbi_count_var: Output variable for the count of observed NBI deprivations.
nbi_var: Output NBI poverty flag.
extreme_nbi_var: Output extreme NBI poverty flag.
overwrite: Logical. If TRUE, overwrite existing output variables.
strict_binary: Logical. If TRUE, require all non-missing component values to be binary 0/1.

Value

A data frame with NBI flags and an nbi_flag_policy attribute.
