Jun Qing <[email protected]> asked how to apply time-series settings to
multiply-imputed data:

It looks like Jun has MI data in the -ice- format. In Stata 11 we can import
-ice- data with the -mi import ice- command. Then we can use -mi tsset-, which
applies time-series settings to data in -mi- format. The help files for the
commands are -help mi import ice- and -help mi tsset-.
