Trying to interpret this months later... I'm pretty sure the PGM conventions refer to
- not distinguishing "obs" and "mis" quantities at the PGM level
- clarifying that the binomial term is the likelihood associated with obs/mis group membership (as a vector) -- this doesn't translate perfectly to a PGM, where stacks (somewhat) imply independence, but oh well.

In this case, I think moving the obs/mis indicator variables to a vector outside the plates would do it. The conditionals should be such that everything inside the plate is still independent for different sources.
This is one of the requested topics for the upcoming LSSTC DSF session, so I'll have to work it out in the next few weeks anyhow.

Now closed in the dsfp_sep17
branch, although not merged into master.

Updated issue! Come up with better example scenarios than the M-sigma relation. It should be much easier if the missingness mechanism is intuitive and plausible.
Also
- explain why
$I$ is outside the plate in PGMs (easy to forget) - requires more than 1 class to do justice (I think we already knew that)
from statisticalmethods.
Hopefully closed by 33b4cc0
- Put
$I$ inside in the end (and$N_{obs}$ outside - Example is now cluster scaling relations
- Some changes since dsfp version inspired by recent paper on fitting truncated data
