Examples of concordant in the following topics:

  • Other Types of Correlation Coefficients

    • Other types of correlation coefficients include intraclass correlation and the concordance correlation coefficient.
    • The concordance correlation coefficient measures the agreement between two variables (e.g., to evaluate reproducibility or for inter-rater reliability).
    • Whereas Pearson's correlation coefficient is immune to whether the biased or unbiased version for estimation of the variance is used, the concordance correlation coefficient is not.
    • The concordance correlation coefficient is nearly identical to some of the measures called intraclass correlations.
    • Distinguish the intraclass and concordance correlation coefficients from previously discussed correlation coefficients.
  • Rank Correlation

    • The observations are sadi to be concordant if the ranks for both elements agree—that is, if both $x_i > x_j$ and $y_i > y_j$, or if both $x_i < x_j$ and $y_i < y_j$.
    • The observations are neither concordant nor discordant if $x_i = x_j$ or $y_i = y_j$.
    • $\displaystyle{\tau = \frac{(\text{number of concordant pairs}) - (\text{number of discordant pairs})}{\frac{1}{2} n (n-1)}}$
  • Comparing Two Populations: Independent Samples

    • Any pair of observations are said to be concordant if the ranks for both elements agree.
    • $\displaystyle{\tau = \frac{(\text{number of concordant pairs}) - (\text{number of discordant pairs})}{\frac{1}{2} n (n-1)}}$
