Plot the cross entropy loss from a cv.strat_cox object — plot.cv.strat_cox • grplasso

Return the plot of the cross entropy loss from a cv.strat_cox object

Usage

# S3 method for class 'cv.strat_cox'
plot(
  fit,
  log.x = T,
  vertical.line = T,
  col.vertical.line = "blue",
  col.dot = "red"
)

Arguments

fit: a cv.strat_cox object.
log.x: whether the horizontal axis be on the log scale.
vertical.line: whether draws a vertical line at the value where cross-validaton error is minimized.

Examples

data(ContTime)
data <- ContTime$data
Event.char <- ContTime$Event.char
prov.char <- ContTime$prov.char
Z.char <- ContTime$Z.char
Time.char <- ContTime$Time.char
cv.fit.strat_cox <- cv.strat_cox(data, Event.char, Z.char, Time.char, prov.char, group = c(1, 2, 2, 3, 3), nfolds = 10)
plot(cv.fit.strat_cox)
