Ok, this is what I get for the version of the estout package: *! version 1.1.0 05nov2008 Ben Jann - So, I have an older version comapred to Maarten. I ran: ssc install estout, replace and the above version was installed. Is there anything else I can do to try and get the 2009 version? Thanks, /Amal. ________________________________________ From: owner-statalist@hsphsun2.harvard.edu [owner-statalist@hsphsun2.harvard.edu] on behalf of Maarten Buis [maartenlbuis@gmail.com] Sent: 11 February 2013 14:35 To: statalist@hsphsun2.harvard.edu Subject: Re: st: Error message when trying to regression model with eststo prefix. You are still mixing up -xi:- and factor variable notation. You should never use the -xi:- prefix in combination with -ib#.varname-. The example I sent before works for me, so if you are running an up to date version -estout- on an up to date version of Stata the problem you have should not happen. So, all I can think of is that you are still running an old version of -estout-. If I type -which estout- I get: *! version 3.13 06aug2009 Ben Jann. -- Maarten On Mon, Feb 11, 2013 at 2:14 PM, Amal Khanolkar <Amal.Khanolkar@ki.se> wrote: > Thanks for the inputs - but problem persists: > > . eststo: xi: logistic verypreterm i.ethnicity2 sex byear if magecat!=. & parity!=. & education!=. & famsit_new2!=. & smoke1!=. & multibirth==1, vce (robust) > i.ethnicity2 _Iethnicity_1-22 (naturally coded; _Iethnicity_1 omitted) > > Logistic regression Number of obs = 1766026 > Wald chi2(23) = 358.39 > Prob > chi2 = 0.0000 > Log pseudolikelihood = -63492.073 Pseudo R2 = 0.0026 > > ------------------------------------------------------------------------------ > | Robust > verypreterm | Odds Ratio Std.
