Hello!

I conducted a mutlilevel analysis with a binary outcome (0/1) in HLM 7 and read that the Adaptive Gaussian Quadrature (AGQ) method leads to better estimates than REML. The model converges, but below the table with the final estimations of variance components in the output its written "Unable to compute AGQ T(hat) for likelihood".

Does that mean I should use a higher number of quadrature points?

So far I've used 100 iterations and 12 quadratur points.

Which estimations might still be biased? The manual of HLM 7 does not provide an explanation for this error term.

Thank you in advance!

Kind regards, Josefine
