function [X, z, mu] = mixBernRnd(d, k, n)
|
|
% Generate samples from a Bernoulli mixture distribution.
|
|
% Input:
|
|
% d: dimension of data
|
|
% k: number of components
|
|
% n: number of data
|

% Output:
|
|
% X: d x n data matrix
|
|
% z: 1 x n response variable
|
|
% mu: d x k parameters of each Bernoulli component
