How can I install dropmiss in STATA?

[karthy thik]

I am very new to STATA, so may I know how to install the dropmiss option in STATA.

[Clyde Schechter]

Start with -findit dropmiss-. That will open a page in the Viewer and you will find several links that look promising. Pick the one that is most current so that you get the most recent version. Click on that link and you will get a page from the source (Stata Journal) that includes a link that says (click here to install).

By the way, -dropmiss- is a command, not an option.

dropmiss (STB, Stata Journal) is considered superseded by missings (Stata Journal).

1. If you subscribe to the Stata Journal, then see http://www.stata-journal.com/article...article=dm0085

2. If you don't subscribe, then access to that paper is USD 11.75 until Q4 2018.

3. Either way, there is an introduction at http://www.statalist.org/forums/foru...aging-missings

4. Either way, you can install using

net from http://www.stata-journal.com/software/sj15-4
net install dm0085

and then a help file is available as usual.

You might also want to look at misstable.

By the way, Stata generally is quite happy having missing values - it simply doesn't use them in estimating models. Dropping missing values may help keep a dataset small or offer other advantages, but is often not necessary.
