I am testing the reliability of the quadrature approximation after
running a random effects logit model. However the relative difference on
3 of my variables exceed 1% (they are 2 job sector dummies with relative
differences of 1.3% and 48% and 1 industry dummy with a relative
difference of 1.3%) . I have increased the quad points (to 20) but this
does not change the results. All other coefficients are fine.

Looking at the example in the book, it appears that if one coefficient
is problematic, the reliability of all the estimates are questionable
whilst reading the FAQ suggest that if all other coefficients are fine
while one may be problematic, I should be reasonably confident with the

Since there does not appear to be much gain in increasing the quad
points, should I be confident with my results even though 3 coefficients
exceeds 1% with one have a relative difference of 48%?

Thanks for any advice
