I'm sorry, I didn't explain myself very well, it's not the predictions themselves but the onscreen estimates from the model table I want to extract. I can't work out how to get these having looked at the help file and the pdfs. I'm sure it's something simple but I really can't find it from these documents. 


Please let me rephrase my question.


I have run the following model 

xi: xtmixed audit monitor i.living || schoolid: monitor i.living, nostd var mle covariance(unstructured)


and I want a way to take the estimates from the on screen model to run, for example

display var(_cons) + 2*cov(living2, _cons) + var(living2)


Another example I have run

xtmixed money centredyear year2 || pupilid: year, variance nostderr mle cov(unstructured)

and want something like this

twoway (function Upper= _b[_cons] + _b[centredyear]*x + _b[year2]*x^2 + (1.96*sqrt(var(_cons)^2 + 2*cov(_cons, centredyear)*x + var(year)*x^2))

	Many thanks,
		Mark
