GetCurves: Density, Survival, and Hazard Estimates

Description

This function estimates mariginal density, survival, and hazard functions given covariates.

Usage

GetCurves(fit, xpred, ygrid, CI=c(0.05, 0.95))

Arguments

fit

an object obtained from functions anovaDDP, spCopulaDDP, indeptCoxph and spCopulaCoxph.

xpred

an npred by p vector of covariates matrix used for curve estimates.

ygrid

a vector of grid points (in log survival time scale) indicating where the curves will be estimated.

CI

a vector to indicate the level of credible interval, where first element indicate the lower probability.

Value

Use names to find out what they are, where fhat represents density, Shat represents survival and Hhat represents hazard.

Details

This function estimates mariginal density, survival, and hazard functions given covariates.
