Please don't SHOUT "no good" is not very informative; tell us exactly what you typed, what Stata told you in return and why you think this is a problem. The key word is _exactly_. please give complete references, author + title is not a complete reference. If your mentor suggested that you ask the authors, than why have you not done so? -- Maarten On Tue, Feb 12, 2013 at 3:01 PM, Frank Lopresti <fl2@nyu.edu> wrote: > I know I'm using correct svyset: command as I replicate the simple stats on > Hookah usage using "svy: table" commands... then I try "svy: logistic" with > age categories dummied out....NO GOOD!!!.... any hints?
