two forage species alfalfa (medicago sativa), and sainfoin (onobrychis viciifolia scop.), at two consecutive growing season (spring and summer), were studied for their chemical composition and in vitro gas production characteristics. data on cumulative gas production (ml gas/g dm) were fitted to the non-sigmoidal model, and for evaluation of model, the concordance correlation coefficient (ccc) ...

A multivariate technique named Canonical Concordance Correlation Analysis (CCCA) is introduced. In contrast to the classical (CCA) which based on maximization of Pearson’s correlation coefficient between linear combinations two sets variables, CCCA maximizes Lin’s concordance accounts not just for maximum but also closeness aggregates’ mean values and their variances. While CCA employs centered...

The concordance correlation coefficient is commonly used to assess agreement between two raters or two methods of measuring a response when the data are measured on a continuous scale. However, the situation may arise in which repeated measurements are taken for each rater or method, e.g. longitudinal studies in clinical trials or bioassay data with subsamples. This paper proposes a coefficient...

On the basis of a high correlation, non-HDL-C (non-high-density lipoprotein cholesterol) and apoB (apolipoprotein B) have been suggested to be of equivalent value for clinical practice; however, the strength of this relationship has not been examined in detail in patients with dyslipidaemia. The present study examines the variance of non-HDL-C compared with apoB in 1771 consecutive patients eva...

The objective of this paper is to evaluate the effectiveness of using Markov switching models to measure the strength of synchronization between business cycles. Synchronization is defined by the fraction of time in which two country’s business cycles are in the same state (concordance) and by the degree to which turning points cluster together (correlation). We use a Bayesian, Gibbs sampling a...

BACKGROUND AND OBJECTIVES Although there is controversy regarding the role of venous oxygen saturation in the initial resuscitation of septic patients with hypoperfusion, these markers are still widely used. This study aimed to evaluate the correlation and concordance between central (SvcO2) and mixed (SvO2) oxygen saturation in septic shock patients with or without hypoperfusion, in addition t...

Clinical studies are often concerned with assessing whether different raters/methods produce similar values for measuring a quantitative variable. Use of the concordance correlation coefficient as a measure of reproducibility has gained popularity in practice since its introduction by Lin (1989, Biometrics 45, 255-268). Lin's method is applicable for studies evaluating two raters/two methods wi...
