calculate_relative_tem: Calculate relative TEM of measurements by multiple observers.

In nutriverse/anthrocheckr: Anthropometric Measurement Standardisation Tests

Calculate relative TEM of measurements by multiple observers.

Description

Calculate relative TEM of measurements by multiple observers.

Usage

calculate_relative_tem(tem, mean_value)

Arguments

tem	A numeric vector or data frame of technical error of measurements produced from applying [calculate_tem_cohort()].
mean_value	A numeric vector or data frame of mean of measurements produced from applying [calculate_mean()].

Value

A vector or data frame of calculated relative TEM per observer and per measurement type.

Examples

## Calculate relative TEM for weight using the smartStd dataset
  tem <- calculate_tem_cohort(df = smartStd,
                              m1 = "weight1",
                              m2 = "weight2",
                              index = "observer",
                              n = 10)

  x <- smartStdLong[smartStdLong$measure_type == "weight", ]

  mean_value <- calculate_mean(measures = x$measure_value,
                               index = x[ , "observer"])

  rel_tem <- calculate_relative_tem(tem = tem, mean_value = mean_value)
  rel_tem
