Stata users can rely on the very neat Episens package for sensitivity analysis. Briefly, it allows one to specify a diagnostic tool's sensitivity and specificity and take those into account when estimating a risk ratio, for instance. A full description of the package is available at <http://www.stata-journal.com/sjpdf.html?articlenum=st0138>

Hi everybody, I'm performing a cluster analysis (pkg "cluster") on a dataset which includes 15 variables: is there a way to know how much each variable weighs on the final clustering output? Thanks Alessandro
