- Lins Concordance Correlation - Real Statistics Using Excel
Describes Lin's concordance correlation coefficient and how to calculate it in Excel as well as a confidence interval Also explains how to interpret Lin's CCC
- Users guide to correlation coefficients - PMC - PubMed Central (PMC)
Lin's concordance correlation coefficient (ρ c) is a measure which tests how well bivariate pairs of observations conform relative to a gold standard or another set 7 Lin's CCC (ρc) measures both precision (ρ) and accuracy (Cβ) 8 It ranges from 0 to ±1 similar to Pearson's Altman suggested that it should be interpreted close to other
- Concordance Correlation Coefficient: Definition Interpretations
What is the Concordance Correlation Coefficient? Lin’s concordance correlation coefficient (ρ c) is a measure of how well a set of bivariate data (Y) compares to a “gold standard” measurement or test (X) You can also compare two sets of measurements without a gold standard comparison
- The Concordance Correlation Coefficient - NIRPY Research
The Concordance Correlation Coefficient (CCC) was introduced by Lawrence Lin in 1989 It was developed as a further metric (in addition to the usual Pearson correlation coefficient) to quantify the similarity between two sets of data, for instance a gold standard and a second reading
- Simple Methods for Repeatability and Comparability: Bland-Altman . . . - SAS
Regression analysis can be used to predict the measurement of one method from the measurement obtained by another method, which is more of a calibration approach rather than answering a question of comparability of the methods
- 18. 6 - Concordance Correlation Coefficient for Measuring Agreement
The concordance correlation coefficient, \(r_c\) , for measuring agreement between continuous variables X and Y (both approximately normally distributed), is calculated as follows: \(r_c=\dfrac{2S_{XY}}{S_{XX}+S_{YY}+(\bar{X}-\bar{Y})^2}\)
- Lin’s Concordance Correlation Coefficient - NCSS
Lin’s concordance correlation coefficient (CCC) is the concordance between a new test or measurement (Y) and a gold standard test or measurement (X) This statistic quantifies the agreement between these two measures of the same variable (e g , chemical concentration) Like a correlation, CCC ranges from -1 to 1, with perfect agreement at 1
- Concordance Correlation Coefficient
Lin’s Concordance Correlation Coefficient (CCC) can be computed as 1 minus the ratio of the expected orthogonal squared distance from the line y = x to the expected orthogonal squared distance from the line y = x assuming independence
- Concordance Correlation Coefficient - R-bloggers
In fact, analogous to how a Pearson correlation coefficient ρ = 1 ρ = 1 signifies perfect positive correlation, a CCC of 1 designates that the paired observations fall exactly on the line of perfect concordance (i e , the 45-degree diagonal line)
- Concordance correlation coefficient calculation in R - Medium
What is the Concordance Correlation Coefficient? The CCC, introduced by Lin in 1989, measures the degree of agreement and correlation between two sets of data points It provides a single
