)

Arguments

r	a numeric value, a seed to run this method
data	a dataframe, the data used to performance this survival model
cvK	a numeric value, cross-validation fold
fitform_ogl	a Surv object from package survival, the survival function
formula1	a Surv object from package survival, to caulculate a version of the brier score, details please check package pec
formula2	a Surv object from package survival, to caulculate a version of the brier score, details please check package pec
formula3	a Surv object from package survival, to caulculate a version of the brier score, details please check package pec
formula4	a Surv object from package survival, to caulculate a version of the brier score, details please check package pec
time1	a numeric value, the time point to calculate the risk, see package "CoxBoost"
timess	a numeric vector of length 15, contains time points to get the time-dependent AUC values
stepnumber	a numeric value, the number of stpes performed in the model, see package "CoxBoost"
penaltynumber	a numeric value, the penalty number used in the model, see package "CoxBoost"

Value

a data.frame with allevaluation measurements in all columns and rows are each fold results from cross-validation

Examples

data("exampledt", package = "SurvBenchmark")
fitform_ogl=survival::Surv(time,status)~.
formula1=fitform_ogl
formula2=fitform_ogl
formula3=survival::Surv(time,status)~1
formula4=survival::Surv(time,status)~1
form1=as.formula(~.)
timess=seq(as.numeric(summary(cancerdt2_1$time)[2]),as.numeric(summary(cancerdt2_1$time)[5]),(as.numeric(summary(cancerdt2_1$time)[5])-as.numeric(summary(cancerdt2_1$time)[2]))/14)
time1=timess[3]
stepnumber=10
penaltynumber=100
want=cox_boost_fun(1,cancerdt2_1[,-dim(cancerdt2_1)[2]],5,fitform_ogl,formula1,formula2,formula3,formula4,time1,timess,stepnumber,penaltynumber);
