In mknoll/dataAnalysisMisc: Collection of functions for daily tasks

Find two differening groups in survival data

Description

Tests different cutoffs on a continuous variable and calculates log-rank tests / survival differences

Usage

findOptCutoff_Model(
  data,
  srv,
  frm0 = "srv~1",
  frm = "srv~GRP",
  stdVar = "VAL",
  delta = 0.1,
  minGrpSize = 1,
  subjVar = NULL,
  dist = NULL
)

Arguments

data	data.frame, with variables in cols
srv	Surv object with the corresponding data
delta	proportion in which group splitting should be performed
minGrpSize	minimum group size for cutoffs
subject	subject IDs if multiple measurements per subjects are to be tested

Value

data.frame with the calculated survival values (p.value, median survival, group sizes, cutoffsize, stepsize)
