Returns variance-covariance matrix of Cox Proportional Hazard model.

Description

returns a variance-covariance matrix of Cox Proportional Hazard model from the server side environment.

Usage

vcovDS.coxph(object = NULL)

Arguments

object

name of server-side coxph object.

Details

Serverside aggregate function vcovDS.coxph called by clientside function ds.vcov.coxph. returns a list which contains a variance-covariance matrix for a Cox model. This request is not disclosive, because the disclosure checks should be performed in the main function for building the Cox model (e.g. checking for over saturation). For further details see help for the native vcov function.

Value

a variance-covariance matrix.
