Without comment on whether the detail here is correct, it sounds like a
case for controlling which observations you feed via
... if !missing(x1, x2, x3, x4)

I'd like to calculate the matches between observations across a set of
binary variables. I suspect that there are multiple ways to do this.
I've specified:
matrix dissimilarity m=x1 x2 x3 x4, match proportion
However, some values in x1-x4 are missing. Based on the results, it
appears that Stata treats missing values as if they were 1 and I don't
see how to modify that. I'd like to calculate to calculate similarities
across only non-missing elements (the number of which will be different
for each pair, of course).
