plot.SuperLearner: Plot estimated risk and confidence interval for each learner

Description

Does not include SuperLearner or Discrete SL results as that requires CV.SuperLearner to estimate the standard errors.

Usage

# S3 method for SuperLearner
plot(x, Y = x$Y, constant = qnorm(0.975),
  sort = TRUE, ...)

Arguments

x

SuperLearner result object

Y

Outcome vector

constant

Multiplier of the standard error for confidence interval construction.

sort

If TRUE re-orders the results by risk estimate.

...

Any remaining arguments (unused).

Value
