Following is a response from DHS Research & Data Analysis Director, Tom Pullum:

You are asking questions that go beyond DHS data and therefore beyond the scope of the forum.

DHS has very low levels of "missing" data. A blank or dot in a DHS data file should be interpreted as Not Applicable (NA). If you are thinking of "missing" as "don't know" or "refused" or something like that, we use special codes such as 8, 9, 9994, etc., depending on the variable. The frequencies of those codes are usually very low.

In general, to test whether "missing" is random with respect to some potential covariate, you construct a binary variable that is 1 if "missing" and 0 if "not missing" and do a logit regression of that variable on the covariate, to see whether there is a statistically significant relationship.
