st: Drawing a graph of ROC curve from statistics after a somersd command

[Katy Keenan <keenan.katy@googlemail.com>]

Hi,

I am calculating ROC AUC statistics to compare logistic regression
models from complex survey data, using the somersd command.
I was wondering if anybody knows a way of drawing a ROC curve graph to
viusally compare several curves after I have run the somersd command.

Thanks in advance,
