I would look for some reason why there just isn't enough
information on these observations to estimate the necesary
models. Having no observed values is an obvious candidate
but other patterns might also do the trick. However, it is
very hard for us to diagnose the problem given the 
information you can give us via this list. This is almost 
certainly a case where you'll just need to share the data 
with someone who knows these techniques, so they can take 
a look at your specific case. The obvious candidate is

Hope this helps,
