rmvbinary_EP: Simulating correlated binary variables using the algorithm by Emrich and Piedmonte (1991)

Description

Generation of random sample of binary correlated variables

Usage

rmvbinary_EP(n, R, p)

Value

Sample (n x p)-matrix with representing a random sample of size n from the specified multivariate binary distribution.

Arguments

n

Sample size

R

Correlation matrix

p

Vector of marginal probabilities

Author

Jochen Kruppa, Klaus Jung

Details

The function implements the algorithm proposed by Emrich and Piedmonte (1991) to generate a random sample of d (=length(p)) correlated binary variables. The sample is generated based on given marginal probabilities p of the d variables and their correlation matrix R. The algorithm generates first determines an appropriate correlation matrix R' for the multivariate normal distribution. Next, a sample is drawn from N_d(0, R') and each variable is finnaly dichotomized with respect to p.
