Covariance matrix for binary variables

Description

Covariance matrix for binary variables

Usage

binary_cov_matrix(x, ncores = 2)

Arguments

x	a matrix or data.frame containing only binary variables.
ncores	(optional) number of cores to be used.

Value

covariance matrix.

Examples

N <- 100
M <- 1000
X <- matrix(rbinom(n = N*M, size = 1, p = .234), ncol = N, nrow = M)
covmat.binary <- binary_cov_matrix(X)
covmat.default <- var(X)
plot(covmat.binary ~ covmat.default)
abline(a = 0, b = 1, lty = 2)
