lcc (version 3.2.2)

vcov.lcc: Extract Variance-Covariance Matrix of the Fixed Effects for an lcc Object

Description

Extracts the variance-covariance matrix of the fixed effects from a fitted lcc model object. This function provides insights into the variability and covariance structure of the fixed effects in the model.

Usage

# S3 method for lcc
vcov(object, ...)

Arguments

object

An object of class lcc, representing a fitted longitudinal concordance correlation model.

...

Optional arguments passed to the vcov.lme function from the nlme package.

Details

The function specifically retrieves the variance-covariance matrix associated with the fixed effects of the lcc object, which is useful for understanding the relationship between these effects. For more details on variance-covariance matrices, refer to the methods for nlme objects.

           method = "Method", time = "Time", qf = 2, qr = 2)
vcov(fm1)
