In that case you can look at the binomial distribution: *------------------ begin example ------------------ sysuse nlsw88, clear gen p = invlogit(-3+ .1*grade) gen var = rbinomial(33,p) + 1 corr grade var spikeplot var *------------------- end example ------------------- (For more on examples I sent to the Statalist see: http://www.maartenbuis.nl/example_faq ) Hope this helps, Maarten --------------------------------- Maarten L.
