repeatability | R Documentation |
Estimate the repeatability of a measure's scores across two time points.
repeatability(measure1, measure2)
measure1 |
Vector of scores from the measure at time 1. |
measure2 |
Vector of scores from the measure at time 2. |
Estimates the coefficient of repeatability (CR), bias, and the lower and upper limits of agreement (LOA).
Dataframe with the coefficient of repeatability (CR
), bias, the lower
limit of agreement (lowerLOA
), and the upper limit of agreement
(upperLOA
). Also generates a Bland-Altman plot with a solid black
reference line (indicating a difference of zero), a dashed red line
indicating the bias, and dashed blue lines indicating the limits of
agreement.
