Art Burke <art.burke@educationnorthwest.org> would like to obtain variances from
-mi estimate: xtmixed-:
> This command ...

> yields this output ...
> ------------------------------------------------------------------------------
> Random-effects Parameters | Estimate Std. Err. [95% Conf. Interval]

> sd(Residual) | .5989765 .003953 .5912786 .6067746
> ------------------------------------------------------------------------------
The -mi estimate- command has its own reporting options. The -variance- option
that Art needs is the option of -mi estimate-, which must be specified in the
-mi estimate- prefix:
. mi estimate, variance: xtmixed overtvic || school_code: , mle
The -var- option in Art's command affects only the output of -xtmixed-, which is
suppressed by default. (Art may display the output by using the -noisily-
option of -mi estimate-.)
