msaenet.sim.poisson: Generate Simulation Data for Benchmarking Sparse Regressions (Poisson Response)

Description

Generate simulation data for benchmarking sparse Poisson regression models.

Usage

  n = 300,
  p = 500,
  rho = 0.5,
  coef = rep(0.2, 50),
  snr = 1,
  p.train = 0.7,
  seed = 1001
)

Value

List of x.tr, x.te, y.tr, and y.te.

Arguments

n
