I'm not even sure if this is the right place to ask and even if it is, I'm well aware it is a bit of a stretch, but anyways:
I'm looking for the article "Asymptotic properties of robust generalized M-estimates for the first order autoregressive parameter" from 1976 (or 1977) by R.D. Martin and J. Jong (sometimes also cited as J. de Jong). The catch is that it seems to only be availabe in the form of a Bell Labs Technical Memo and I haven't been able to find it online or as physical copy anywhere. I also tried sending an email to the author I was able to find (Prof. Martin, the other author seems to have left the academic world), but unfortunately did not receive a response.
The article has 20 citations, some of them quite recent even, so I'm hoping that for some miraculous reason somebody here might be able to help me out. Thanks in advance.
