check.structure_post_frailty_var: Check Structure of Posterior Frailty Variances

In TimeDepFrail: Time Dependent Shared Frailty Cox Model

Check Structure of Posterior Frailty Variances

Description

The function controls that the structure of the 'Posterior Frailty Variances' coincides with the theoretical one.

Usage

check.structure_post_frailty_var(post_frailty_var, n_intervals, n_centres)

Arguments

post_frailty_var	Posterior frailty variances S3 object of class 'PFV.AdPaik', composed of three elements: 'alphaVar': posterior frailty variance for \alpha_j, \forall j. It is a vector of length equal to the number of centres. 'epsVar': posterior frailty variance for \epsilon_{jk}, \forall j,k. It is a matrix of dimension (n_centres, n_intervals). 'ZVar': posterior frailty variance for Z_{jk} = \alpha_j + \epsilon_{jk}, \forall j,k. It is a matrix of dimension (n_centres, n_intervals)
n_intervals	Number of intervals of the time-domain
n_centres	Number of centres/clusters.

Value

An error if any condition is not satisfied.
