error_structure {mvord}

Extracts Error Structure of Multivariate Ordinal Regression Models.

Description

A generic function which extracts for each subject the estimated error structure parameters from objects of class 'mvord'.

Usage

error_structure(eobj, type, ...)

## S3 method for class 'mvord'
error_structure(eobj, type = NULL, ...)

Arguments

eobj

an object of class 'mvord'.

type

choose type "sigmas", "alpha", "corr", or "z".

...

further arguments passed to or from other methods.

Details

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.
