ccc_est {cccrm}R Documentation

Concordance correlation Coefficient estimation from a linear mixed model

Description

It computes the Concordance Correlation Coefficient and its asymptotic confidence interval.

Usage

ccc_est(model, D = NULL, cl = 0.95, transf = "F2", sd_est = TRUE, ...)

Arguments

model

The lme model.

D

Weights vector.

cl

Confidence level (0.95 as a default). Bounded between 0 and 1.

transf

Character string. Whether to apply a transformation of the coefficient for inference. Valid options are: "F" for Fisher's Z-transformation; "F2" For Fisher's Z-transformation setting m=2 (default); "KG" Konishi-Gupta transformation; "None", no transformation is applied. See *Details* for further information.

sd_est

Logical. Whether to estimate the asymptotic standard deviation (defaults to TRUE) or to only report the ccc value.

...

To pass further arguments.

Value

A ccc class object.
