st: Problems with ci_marg_mu and ordinal variable |

Dear all, I am trying to get confidence intervals for my multilevel model, using gllamm, gllapred and finally the "ci_marg_mu" command. My model is: gllamm demobilize length_stay education econ_stabilty, i( region_birth_n) link(ologit) adapt eform I then use gllapred with the "marginal" und "mu" option to obtain predicted probabilities. Since I am using an ordinal dependent variable, I also specify the "above ()" option. gllapred prob0, marginal mu above(0) gllapred prob1, marginal mu above(1) And here is where I get stuck. When I try to get the prediction intervals with the "ci_marg_mu" command, STATA tells me: ci_marg_mu lower upper "must specify above() option for ordinal responses" However, apparently the "above" option is no allowed with the ci_marg_mu command as stata tells me: ci_marg_mu lower0 upper0, above(0) option above() not allowed What am I doing wrong? How can I specify the above option? I am using Stata 11 for Mac. Thank you very much for any advice!
