variable _mi_miss not found

[Hillel Alpert]

I am attempting to import imputed data into a data set using the command, mi import wide. It results in the following error message.

data already -mi set-
r(459);

I attempted to "unset" the data using the command, mi extract 0, but it results in the error message:

variable _mi_miss not found
r(111);

I would very much appreciate instruction on how to overcome the error and import the data.

To unset the data try,

mi unset

clear
use https://stats.idre.ucla.edu/wp-content/uploads/2017/05/hsb2_mar
mi set wide
mi unset

[Rich Goldstein]

you may need to use the "asis" option to the -mi unset- command; see the help for this option in

help mi unset
