I am analysing a logistic regression model, binary outcome. I want to analyse the adjusted proportion of the outcome for a binary (0/1) covariate. I run the logistic model followed by margins . logistic dod30dgr i.lapscopiintent alder aldersq........ . margins lapscopiintent I get an error 'lapscopiintent' not found in list of covariates r(322); If I put i. before the binary variable I am interested in . logistic dod30dgr i.lapscopiintent alder aldersq................ . margins lapscopiintent Predictive margins Number of obs = 166811 Model VCE : OIM Expression : Pr(dod30dgr), predict() Delta-method Margin Std.
