compute_ph_y_anthr__height_mean: Compute "Anthropometrics [Youth] (Height): Mean"

In ABCDscores: Summary Scores of the Adolescent Brain Cognitive Development (ABCD) Study

Compute "Anthropometrics [Youth] (Height): Mean"

Description

Computes the summary score ph_y_anthr__height_mean Anthropometrics [Youth] (Height): Mean

• Summarized variables:

  • ph_y_anthr__height__r01_001

  • ph_y_anthr__height__r02_001

  • ph_y_anthr__height__r03_001

• Excluded values: none

Calculation

There are at most 3 possible measurements, and the calculation is as follows:

• 0 missing, find the max and min of the three, and take the average of the min and max. Then compare the average to the third value.

  • third value < average -> mean(min, third value)

  • third value > average -> mean(max, third value)

  • third value = average -> third value

• 1 missing, mean of the rest two

• 2 missing, use the last one

• 3 missing, NA

Usage

vars_ph_y_anthr__height

compute_ph_y_anthr__height_mean(
  data,
  name = "ph_y_anthr__height_mean",
  combine = TRUE
)

Arguments

data	tbl, Dataframe containing the columns to be summarized.
name	character, Name of the new column to be created. Default is the name in description, but users can change it.

Format

vars_ph_y_anthr__height is a character vector of all column names used to compute summary scores of ph_y_anthr__height.

Value

tbl. The input data frame with the summary score appended as a new column.
