Dear kit (love that name!), scott m., and joseph c.,

Thank you for the responses. I utilized each of the various command language
suggestions with success. I have the hamilton book already and am up to
regression diagnostics. How I missed -drawnorm-, as well, I would hope only
attests to reaching absorption levels over the last couple of months as a
new Stata user and is not a prediction regarding long term skill! I did have
one startling moment of cold sweated chill when I read a note a few days
back (I have become an avid statalist reader since purchasing the software)
within which nick(-mysterious, prickly, brilliant, beloved-) referred to
himself during a recent statalist exchange as a '...nonstatistician,..' !
Goodness, now that gave me a fright!

After reviewing the faq's and the archive I've been unable to find 
Guidance or a module that would assist in generating data sets from scratch
or at least near it. For instance....

Kit wrote

. set obs 109
obs was 0, now 109

. g double v1 = 1.74*invnorm(uniform())+10.62

. su

     Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
           v1 |       109     10.6402    1.734998   6.296962   14.36916



This would work better with a larger sample:

. set obs 10900
obs was 0, now 10900

. g double v1 = 1.74*invnorm(uniform())+10.62

. su

     Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
           v1 |     10900    10.61984    1.736441   3.801061   17.71306
