require(ELMSurv)
require(survival)
#Lung DATA
data(lung)
lung=na.omit(lung)
lung[,3]=lung[,3]-1
n=dim(lung)[1]
L=sample(1:n,ceiling(n*0.5))

rii=c(2,3)
# Default with lin_kernel 
elmsurvmodel=ELMCoxBAR(x=trset[,-rii],y=Surv(trset[,rii[1]], trset[,rii[2]]))
# with  the RBF kernel
elmsurvmodel=ELMCoxBAR(x=trset[,-rii],y=Surv(trset[,rii[1]], 
trset[,rii[2]]),Kernel_type="RBF_kernel",Kernel_para=c(2,1))
#The predicted linear predictor
