Simulation for a regression toy examples from Random Machines Regression 3
Description
Simulation toy example initially found in Scornet (2016), and used and escribed by Ara et. al (2022).
Inputs are 4 independent variables uniformly distributed on the interval [-1,1]. Outputs are generated following the equation
Y= -\sin({X}_{1})+{X}^{2}_{2}+{X}_{3}-e^{{-X^{2}_{4}}} + \varepsilon, \varepsilon \sim \mathcal{N}(0,0.5)
Usage
sim_reg3(n, sigma)
Arguments
n |
Sample size |
sigma |
Standard deviation of residual noise |
Value
A simulated data.frame with two predictors and the target variable.
