Abstract

We are interested in generating binary data via specifying the marginals and the correlation matrix only. However, from a practical point of view it is not obvious how to construct such a matrix, since it has to be positive (semi-)definite and satisfy some special conditions as well. Hence, using R, a free implementation of the S statistical language, we give a graphical interface to input specific marginals and correlations and to change the given "not working" correlation matrix to a possibly "working" one.
