getVarCov.lcc {lcc}

Extract Variance Components from a Fitted Model

Description

Extract Variance Components from a Fitted Model

Usage

## S3 method for class 'lcc'
getVarCov(obj, type, ...)

Arguments

obj

an object inheriting from class lcc, representing a fitted longitudinal concordance correlation function.

type

specifies the type of variance covariance matrix. If type = "random.effects", the default, extract the random-effects variance-covariance; if type = "conditional" extract the conditional variance-covariance of the responses; and if type = "marginal" extracts the the marginal variance-covariance of the responses.

...

optional arguments passed to the getVarCov function.

Details

See methods for nlme objects to get more details.

Value

Returns the variance-covariance matrix of a fitted lcc model object.
