Calculates Lin's concordance correlation coefficient (LCCC) from observed and
predicted values.
Usage
lccc(o, p)
Arguments
o
A numeric vector. Observed values.
p
A numeric vector. Predicted values.
Value
Lin's concordance correlation coefficient (LCCC).
Details
Interpretation: Lin's concordance correlation coefficient (LCCC) can take values
between -1 and 1. LCCC-values close to 1 indicate a strong concordance between
predicted and observed values, while LCCC-values near -1 indicate a strong
discordance. LCCC-values close to 0 indicate no concordance. In a plot of
predicted values versus observed values, an LCCC-value of 1 means that the
all data points are on the 1.1-line.
