Simulate covariate matrix with block structure
Description
Simulate covariate matrix with block structure
Usage
simul_x_block(n, p, block_idx, sigma2_x = 1, within_rho = 0.6, btw_rho = 0.2)
Arguments
n |
a positive integer to indicate sample size |
p |
a positive integer to specify the number of covariates |
block_idx |
a vector of positive integers to indicate the block IDs. The length of the vector is p. |
sigma2_x |
a positive numeric scalar for variance of the covariates |
within_rho |
a numeric scalar between 0 and 1 for the within block correlation |
btw_rho |
a numeric scalar between 0 and 1 for the between block correlation |
Value
a list object of the following
- x
covariate matrix of dimension n by p
- n
sample size
- p
number of covariates
- sigma2_x
variance
- within_rho
within block correlation
- btw_rho
between block correaltion
- block_idx
