In BayesReversePLLH: Fits the Bayesian Piecewise Linear Log-Hazard Model

Samples from the PEH Cox model with a patient covariate vector.

Description

Samples from the Piecewise Linear Log-Hazard (PLLH) Cox model and returns a list containing posterior parameters and posterior restricted mean survival.

Usage

BayesPiecewiseHazardTrt(Y, I1, Trt, Poi, B)

Arguments

Y	Vector of event or censoring times.
I1	Vector of event indicators.
Trt	Vector containing patient treatment/control assignment.
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 treatment coefficient, (6) the mean restricted survivial time of the control therapy, (7) the mean restricted survival time of the treatment therapy.

Examples

Y=rweibull(20,4,1)
I=rbinom(20,1,.5)
Trt=rbinom(20,1,.5)
##Hyperparameter for number of split points
Poi=5
##Number of iterations for MCMC
B=200
