In topycyao/Xsurv: A package used to model survival data from advanced machine learning algorithms

This function allows you to find risk level automatically with lgbcv object.

Description

This function allows you to find risk level automatically with lgbcv object.

Usage

Xsurv_sim_data(size, dim, lambda = NULL, vu = 1, beta = NULL, c_rate)

Arguments

size	sample size of the simulation data
dim	dimension of parameters
lambda	scale parameter
vu	shape parameter,defaut is 1 for exponential distribution
beta	coefficients
c_rate	approximate censor rate

Value

a simulated dataframe

Examples

#
sim_dat<-Xsurv_sim_data(size=500,dim=20,lambda=2,vu=1,
                                    c_rate=0.3)


sim_x<-sim_dat[,1:20]
sim_y<-sim_dat[,c(21,22)]

fit<-Xsurv.cv(sim_x,sim_y,top_n=5)
