The specific methodological aims of our research are: 1) to clarify statistical inference procedures used by R-DAS to produce confidence interval estimates; 2) to review a simple solution to some of the research questions not currently addressed by R-DAS (i.e., with respect to tests of significance); and 3) to describe how in certain situations the percentages and the corresponding standard errors, which are suppressed from the R-DAS output due to the confidentiality concerns can be estimated “by hand”.
