sim_data {rfinterval}

Simulate data

Description

Simulate data for illustrate the performance of prediction intervals for random forests

Usage

sim_data(n = 500, p = 10, rho = 0.6, predictor_dist = "correlated",
  mean_function = "nonlinear-interaction",
  error_dist = "homoscedastic")

Arguments

n

Sample size

p

Number of features

rho

Correlation between predictors

predictor_dist

Distribution of predictor: "uncorrelated", and "correlated"

mean_function

Mean function: "linear", "nonlinear", and "nonlinear-interaction"

error_dist

Distribution of error: "homoscedastic", "heteroscedastic", and "heavy-tailed"

Value

a data.frame of simulated data

Examples

train_data <- sim_data(n = 500, p = 10)
test_data <- sim_data(n = 500, p = 10)
