BayesPiecewiseHazard {BayesReversePLLH}

Samples from the PEH model without covariates.

Description

Samples from the Piecewise Exponential Hazard (PEH) model and returns a list containing posterior parameters and posterior restricted mean survival.

Usage

BayesPiecewiseHazard(Y, I1, Poi, B)

Arguments

Y

Vector of event or censoring times.

I1

Vector of event indicators.

Poi

Prior mean number of split points.

B

Number of iterations for MCMC.

Value

Returns a list containing posterior samples of (1) the split point locations, (2) the log-hazards at each split point, (3) the number of split points, (4) the variance parameter for the log-hazard values, (5) the posterior mean restricted survivial time.
