mgc.sims.exp: Exponential Simulation

In mgc: Multiscale Graph Correlation

Description

A function for Generating an exponential simulation.

Usage

mgc.sims.exp(n, d, eps = 10, ind = FALSE, a = 0, b = 3)

Arguments

n	the number of samples for the simulation.
d	the number of dimensions for the simulation setting.
eps	the noise level for the simulation. Defaults to 10.
ind	whether to sample x and y independently. Defaults to FALSE.
a	the lower limit for the range of the data matrix. Defaults to 0.
b	the upper limit for the range of the data matrix. Defaults to 3.

Value

a list containing the following:

X	[n, d] the data matrix with n samples in d dimensions.
Y	[n] the response array.

Details

Given: w[i] = 1/i is a weight-vector that scales with the dimensionality. Simulates n points from Linear(X, Y), where:

X ~ U(a, b)^d

Y = exp(w^T X) + κ ε

and K = 1 if d=1, and 0 otherwise controls the noise for higher dimensions.

Examples

library(mgc)
result  <- mgc.sims.exp(n=100, d=10)  # simulate 100 samples in 10 dimensions
X <- result$X; Y <- result$Y
