Array
Hi all! I want to drop cases if the percentage of missing is greater than certain value according to key variables.

For example, in Belgium and other courties (variable cid), the percentage of missing on the key variable eat is great than 50%. I do not want include the cases into logit model, how can I do?

I installed missings command deveolped by Nicholas J. Cox(https://www.stata-journal.com/articl...article=dm0085), and did not figure out, perpaps my question is beyond the missings command.

Anyone can give me some advices?
