randomForestCI
Confidence intervals for random forests using the infinitesimal jackknife, as developed by Efron (2014) and Wager et al. (2014).
To install this package in R, run the following commands:
install.packages("devtools")
library(devtools)
install_github("swager/randomForestCI")Example usage:
library(randomForestCI)
# Make some data...
n = 250
p = 100
X = matrix(rnorm(n * p), n, p)
Y = rnorm(n)
# Run the method
rf = randomForest(X, Y, keep.inbag = TRUE)
ij = randomForestInfJack(rf, X, calibrate = TRUE)
