SurvRank (version 0.1)

innerAUC_fct: Calculates inner and outer survival AUCs of training and testset

Description

work-horse function for all ranking methods with inner and outer CV loops

Usage

innerAUC_fct(f, data, t, cv.out, cv.in, i, fold, data.out, nr.var, out.s, sd1, c.time, ranking, used.rank, used.rank1se, pred.in, pred.out, pred.out1, auc.out, auc.out1)

Arguments

f

ranking function

data

data input

t

current t.times argument

cv.out

number of outer CV

cv.in

number of inner CV

i

current counter index

fold

current fold

data.out

training data of outer CV

nr.var

maximum number of variables into model

out.s

predefined output matrix for inner tAUC evaluations

sd1

factor to which sparser solutions should be chosen. Not maximum Survival AUC in inner loop is used in stepwise selection, instead max(survAUC)*sd1 leading to sparser solutions

c.time

as defined in package survAUC time; a positive number restricting the upper limit of the time range under consideration.
