Ignore last post, have just had another google search and found this helpful thread:

http://statalist.1588530.n2.nabble.com/mim-and-parmest-td5013352.html

from Martin Weiss which shows that mim does not store estimates in e(b) rather e(MIM_Q).

Updated code is this:

proportion stage
matrix bmat = e(MIM_Q)
forval j = 1/4 {
gen prop`j' = bmat[1,`j']
}
sum prop*
collapse (mean) prop*

Best wishes

Tim

Having tried both methods suggest by Maarten and Richard, I think Richard's will work best, but I have a problem in that I am using this on a multiple imputed dataset. When I run the analysis, I am returned with an error (details below):

mim: proportion stage if _mj>0 & inrange(yydx,1985,1989)
matrix bmat = e(b)

last estimates not found
r(301)

yet when I run this:

proportion stage if _mj>0 & inrange(yydx,1985,1989)
matrix bmat = e(b)
forval j = 1/4 {
gen prop`j' = bmat[1,`j']
}
sum prop*
collapse (mean) prop*

 
Its absolutely fine - but not what I want.

Any suggestions appreciated.

The estimates are ereturned in e(b). If nothing else you could 
generate variables equal to those values, cut your data set down to 
one case, and save under a new name. Something like

sysuse auto
proportion rep78 , over(foreign)
matrix bmat = e(b)
forval j = 1/10 {
gen prop`j' = bmat[1,`j']
}
sum prop*
