A concordance correlation coefficient to evaluate reproducibility.

Lin, Lawrence I-Kuei·1989·Biometrics

Abstract

A new reproducibility index is developed and studied. This index is the correlation between the two readings that fall on the 45 degree line through the origin. It is simple to use and possesses desirable properties. The statistical properties of this estimate can be satisfactorily evaluated using an inverse hyperbolic tangent transformation. A Monte Carlo experiment with 5,000 runs was performed to confirm the estimate's validity. An application using actual data is given.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • All parameters used for the proposition and cross-validation of the model confirmed their validity for the studied population.

    “and all parameters used for the proposition and cross-validation of the model confirmed their validity for the studied population (15, 37–39, 57)”
  • Explicit maximisation of the concordance correlation coefficient (rho_c) in the model improves emotion prediction compared to optimising the mean square error objective.

    “Furthermore, we suggest using explicit maximisation of the concordance correlation coefficient ( ρ c ) [9] in our model and show that this improves performance in terms of emotion prediction compared to optimising the mean square error objective, which is traditionally used.”
  • Cohen's quadratically weighted kappa coincides with Lin's bivariate concordance correlation coefficient.

    “showing that Cohen's quadratically weighted kappa coincides with Lin's bivariate concordance correlation coefficient (Lin, 1989).”
  • If available, test-retest data are extremely helpful, as they can help prioritize features on the basis of their reproducibility.

    “If available, test-retest data are also extremely helpful, as they can help prioritize features on the basis of their reproducibility (51,52).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
