Description

Find cutoff for predictive case.

Usage

seqlr.find.cutoff.pred(data, yvar, censorvar, xvar, trtvar, type, class.wt, dir,
  nsubj, min.sigp.prcnt)

Arguments

data	input data frame.

xvar	name of predictor for which cutpoint needs to be obtained.
trtvar	treatment variable name.
type	"c" continuous; "s" survival; "b" binary.
class.wt	vector of length 2 used to weight the accuracy score , useful when there is class imbalance in binary data defaults to c(1,1).
