The repeatability coefficient (CR) (Bland Altman) is used to report repeatability understood as the index that compares measurements with the same subject, the same observer and in a short space of time.
The standard error of the measurement is used to report the reliability of an instrument or scale. That is, several measurements of several subjects using one scale or instrument.
Both are absolute measurements supporting their practical usefulness.
But how would the two results be interpreted at the same time? I am getting a great result in terms of CR, but low in SEM in terms of reliability.
Maybe I should adjust the SEM to SEM95, since the CR has that adjustment intrinsically?
