extract_longitudinal_parameters R Documentation
Extract fitted covariance parameters
Description
This function extracts the fitted residual covariance matrices, temporal
correlation parameter, and, when present, fitted random-effects covariance
matrices from a longitudinal surrogate model.
Usage
extract_longitudinal_parameters(object)
Arguments
object
An object of class surrogate_longitudinal_fit.
Value
A list containing fitted covariance parameters, including
rho, V0, V1, and, when present, D0 and D1.
See Also
fit_longitudinal_surrogate_model for a complete example
of fitting a longitudinal surrogate model.
