hds_t {hds}

Hazard discrimination summary estimate at one time point

Description

hds_t estimates HDS at time t under the PH assumption

Usage

hds_t(t, L0hat, betahat, m)

Arguments

t

The time at which to calculate HDS

L0hat

A data frame with variable names of hazard and time. Typically the object returned by basehaz.

betahat

A vector of coefficient estimates from the Cox model. Typically the coefficients value from the coxph.object object returned by coxph.

m

A numeric matrix of covariate values, with a column for each covariate and each observation is on a separate row.
