Clyde B Schechter <> asks if there is a Stata
command which allows to drop specific imputations.

The functionality Clyde is looking for is provided by -mi set-.  To delete
specific imputations, for example, 1, 3, and 5, Clyde can type

  . mi set m -= (1 3 5)

Clyde may also be interested in -mi set M- to delete imputations from the end.
There is a section in -help mi set- describing these two features.
