A generic function which extracts for each subject the estimated
error structure parameters from objects of class 'mvord'.
error_structure(object, type, ...)# S3 method for mvord
error_structure(object, type = NULL, ...)
an object of class 'mvord'.
choose type "sigmas", "alpha", "corr", or "z".
further arguments passed to or from other methods.
sigmas extracts the correlation/covariance matrices corresponding to each subject.
Applicable in line with cor_general, cov_general, cor_equi, cor_ar1.
alpha extracts the parameters of the covariate dependent error structure.
Applicable in line with cor_equi, cor_ar1.
corr extracts the subject-specific correlation parameters. Applicable in
line with cor_equi, cor_ar1.
z extracts the subject-specific Fisher-z score. Applicable in line
with cor_equi, cor_ar1.
