sim_data_log: simulate Poisson matrix

In DongyueXie/stm: Empirical Bayes Poisson Matrix Factorization

simulate Poisson matrix

Description

simulate Poisson matrix

Usage

sim_data_log(
  n,
  p,
  K = 3,
  d = NULL,
  add_background = TRUE,
  background_unif_range = c(1, 2),
  pi0 = 0.8,
  var1 = 1,
  var_e = 0,
  n_simu = 10,
  seed = 12345
)

Details

The DGP is

Y\sim Poisson(\exp(l_0f_0'+LF'+E)),

l_{0i}\sim Uniform(),f_{0j}\sim Uniform(),

l_{ki}\sim N(0,d_k),f_{kj}\sim \pi_0\delta_0 + (1-\pi_0)N(0,\sigma^2_1),

e_{ij}\sim N(0,\sigma^2).
