summary_measure()
|
Get the mean, standard deviation and maximum value of the observations/
measurements made by a single observer across multiple subjects |
calculate_coeff_r()
|
Calculate the coefficient of reliability (R). |
calculate_relative_tem()
|
Calculate relative TEM of measurements by multiple observers. |
calculate_team_tem()
|
Function to calculate technical error of measurement (TEM) when there are
more than two observers involved. |
calculate_tem()
|
Function to calculate technical error of measurement (TEM) based on formula
created by Ulijaszek and Kerr (1999) as an indicator of measurement
precision as described by Mueller and Mortorell (1998). This function is
specific for intra-observer TEM for two measurements, and for inter-observer
TEM involving two measurers. |
calculate_tem_cohort()
|
Function to calculate intra-observer TEM for each observer using input
dataset containing multiple types of multiple measurements from multiple
observers. |
calculate_total_tem()
|
Calculate the Total TEM given individual intra-observer TEM. |
estimate_bias()
|
Calculate the bias of a measurement against a gold standard. Two gold standards
are used in this function: 1) measurements made by a supervisor or a known
expert; and, 2) median of all measurements made by the observers. |
