glmer does not converge, how inaccurate is using nAGQ = 0?

You could use a value of nAGQ that is higher, start with 5 and work
up.

How good the approximation is, depends. If you are having
convergence problems it probably isn't.

Hi

I have a dataset of ~200k piece of hardware tested yearly for 10
years or until failure (~15k). Therefore, the overall dataset
size is ~2,000k. I'm trying to fit a mixed effects logistic model
with glmer, but the model does not converge with the default
settings. I tried to increase the number of max iterations
allowed (from 20 to 100) but still it does not converge. I then
set the nAGQ = 0 and obtained the less accurate estimate of the
model.

My questions would be: Do you have any idea of what parameters I
could modify to try to make the model converge? How inaccurate is
using nAGQ = 0?

Many thanks.
