Estimation parameter fixed effects in a mixed model

[Remy Foulou]

Dear Stata experts,

I work on a mixed model with stata 11.

I don't know how get the estimation of parameters of fixed effects, I only get the estimates of the parameters of the random part (code below).
Is it possible with xtmixed?

xtmixed taille antibioon_t_1##c.agej antibioon_t_2##c.agej antibioon_t_1##c.agej2 antibioon_t_2##c.agej2 ||patient_id: agej agej2, cov(uns) reml

I checked on the help xtmixed but I didn't find.

Thank you in advance for your help,

Rémy

I have never seen that happen. Can you please post the complete output you are getting from Stata with this command? Please place it between code delimiters so that it will be readable. (If you are not familiar with code delimiters, read FAQ #12 for instructions.)
