Test for statistical difference between the proportion of children aged 24 to 59 months old over those aged 6 to 23 months old

Calculate the observed age ratio of children aged 24 to 59 months old over those aged 6 to 23 months old and test if there is a statistically significant difference between the observed and the expected.

Usage

mw_stattest_ageratio(age, .expectedP = 0.66)

Arguments

age: A numeric vector of child's age in months.
.expectedP: The expected proportion of children aged 24 to 59 months old over those aged 6 to 23 months old. By default, this is expected to be 0.66.

Value

A list object with three elements: p for p-value of the difference between the observed and the expected proportion of children aged 24 to 59 months old over those aged 6 to 23 months old, observedR for the observed ratio, and observedP for the observed proportion.

Details

This function should be used specifically when assessing the quality of MUAC data. For age ratio test of children aged 6 to 29 months old over 30 to 59 months old, as performed in the SMART plausibility check, use nipnTK::ageRatioTest() instead.
