I am trying to use -mi-. I run the following with a data set that has not been declared as panel:

qui mi set mlong
qui mi register imputed rule mal94p
qui set seed 29390
mi impute mvn rule mal94p = lat loggdp2 pop100km rel_frac, add(10)

I get the following error:
. mi impute mvn rule mal94p = lat loggdp2 pop100km rel_frac, add(10)
variable year not found
r(111);

I don't have a variable named in the dataset.

Note, when I run the following basic code (e.g,. provided in the manual), Stata performs correctly:

qui use http://www.stata-press.com/data/r11/mheart5
qui mi set mlong
qui mi register imputed age bmi
qui set seed 29390
mi impute mvn age bmi = attack smokes hsgrad female, add(10)

Performing EM optimization:
note: 12 observations omitted from EM estimation because of all imputation variables missing
 observed log likelihood = -651.75868 at iteration 7

Performing MCMC data augmentation ...

Multivariate imputation                 Imputations =       10
Multivariate normal regression                added =       10
Imputed: m=1 through m=10                   updated =        0

Prior: uniform                           Iterations =     1000
                                           burn-in =      100
                                           between =      100

| Observations per m |----------------------------------------------
     Variable |   complete   incomplete   imputed |     total
---------------+-----------------------------------+----------
          age |        142           12        12 |       154
          bmi |        126           28        28 |       154
--------------------------------------------------------------
(complete + incomplete = total; imputed is the minimum across m
of the number of filled in observations.)

Also, my Stata is up to date:


. update query
(contacting http://www.stata.com)

Stata executable
   folder:               D:\Program Files\Stata11\
   name of file:         StataSE.exe
   currently installed:  21 Oct 2009
   latest available:     21 Oct 2009

Ado-file updates
   folder:               D:\Program Files\Stata11\ado\updates\
   names of files:       (various)
   currently installed:  08 Dec 2009
   latest available:     08 Dec 2009

Utilities updates
   folder:               D:\Program Files\Stata11\utilities
   names of files:       (various)
   currently installed:  21 Oct 2009
   latest available:     21 Oct 2009

Recommendation
   Do nothing; all files up to date.

Any ideas?

Best,
John
