You haven't really defined what you mean by "correlation between a series of binary variables" nor have you said anything as to what you plan to do with this information. Possibly a non-parametric measure of correlation such as Kendall's tau will do. Take a look at the function KendallRankCorrelation in the package Statistics`MultiDescriptiveStatistics. -- To reply via email subtract one hundred and four
