Rolf, To make sure somebody speaks to you ? but probably no big India rubber ball [1]. I tried your code with the "nAGQ=0" option, and it fit quickly. The "non-converged" fit under the default was very similar for the point estimates of the fixed effects. Ben should confirm this, but in my experience the nAGQ=0 option is normally pretty good, and it also handles pathological cases when the random effects estimates explode.
Dear Tony, Wow. That does indeed seem to me to be a big red India rubber ball!!! Rapid fit, and the ominous warnings go away. I tried it with the real data --- likewise rapid fit and no warnings. Haven't done any thorough checking of results yet, but it sure looks like progress to me. Thanks hugely! cheers, Rolf
