The longitudinal concordance correlation

Abstract: We present the lcc package, available from the Comprehensive R Archive Network (CRAN). The package implements estimation procedures for the longitudinal concordance correlation (LCC), using fixed effects and variance components estimates from linear mixed models. The LCC is a quantity that measures the extent of agreement between two (or more) methods used to evaluate a response variable of interest and is frequently applied in medicine, pharmacology, and agronomy. The main features of the package are the estimation and inference of the extent of agreement using numerical and graphical summaries.
