Check the plausibility and acceptability of raw MUAC data

Source: R/plausibility_check_muac.R
mw_plausibility_check_muac.Rd

Check the overall plausibility and acceptability of raw MUAC data through a structured test suite encompassing sampling and measurement-related biases checks in the data set. The test suite in this function follows the recommendation made by Bilukha, O., & Kianian, B. (2023).

Usage

mw_plausibility_check_muac(df, sex, muac, flags)

Arguments

df

An object of class data.frame to check. It must have been wrangled using this package's wrangling function for MUAC.

sex

A vector of class numeric of child's sex.

muac

A vector of class double of child's MUAC in centimeters.

flags

A vector of class numeric of flagged records.

Value

A summarized table of class data.frame, of length 9 and width 1, for the plausibility test results and their respective acceptability ratings.

Details

Cut-off points used for the percent of flagged records:

ExcellentGoodAcceptableProblematic
0.0 - 1.0>1.0 - 1.5>1.5 - 2.0>2.0

Examples

## First wranlge MUAC data ----
df_muac <- mw_wrangle_muac(
  df = anthro.01,
  sex = sex,
  muac = muac,
  age = NULL,
  .recode_sex = TRUE,
  .recode_muac = FALSE,
  .to = "none"
)

## Then run the plausibility check ----
mw_plausibility_check_muac(
  df = df_muac,
  flags = flag_muac,
  sex = sex,
  muac = muac
)
