There is a paragraph on using pairwise correlation matrices in
linear regression in Paul Allison (2002) Missing Data. Thousand
Oaks: Sage, pp 8-9, with a number of references to articles from
the '60s and '70s. Main message seems to be that you are not
doing too much dammage if your data is MCAR, but things can go
wrong when the data is MAR. Moreover, there isn't that much
advantage to using pairwise correlaitons when the data is MCAR,
so Paul's conclusion is that the advantages don't outweight the
disadvantages.
