TLDR
It is recommended that sports clinicians and researchers should cite and interpret a number of statistical methods for assessing reliability and encourage the inclusion of the LOA method, especially the exploration of heteroscedasticity that is inherent in this analysis.Abstract:
Minimal measurement error (reliability) during the collection of interval- and ratio-type data is critically important to sports medicine research. The main components of measurement error are systematic bias (e.g. general learning or fatigue effects on the tests) and random error due to biological or mechanical variation. Both error components should be meaningfully quantified for the sports physician to relate the described error to judgements regarding ‘analytical goals’ (the requirements of the measurement tool for effective practical use) rather than the statistical significance of any reliability indicators.read more

Establishing Some Measures of Absolute and Relative Reliability of a Motor Test / Određivanje nekih mjera apsolutne i relativne pouzdanosti motoričkih testova
TL;DR: In this article, the authors discussed relative and absolute reliability of empirical motor data using the Bland-Altman method for determining the limits of agreement and bias between two measurements, and the standard error of measurement (SEM) and the smallest detectable change (SDC) measures.

A Method to Stop Analyzing Random Error and Start Analyzing Differential Responders to Exercise.
TL;DR: This work proposes a method by which differential responders can be classified after accounting for the presence of random error that is quantified from a time-matched control group, and provides easy-to-follow steps and examples to demonstrate how this technique can identify differential responders to exercise.

A concordance correlation coefficient to evaluate reproducibility.
TL;DR: A new reproducibility index is developed and studied that is simple to use and possesses desirable properties and the statistical properties of this estimate can be satisfactorily evaluated using an inverse hyperbolic tangent transformation.
