There are no theorems at work (that I know of), but in my experience this is extremely optimistic. There is also no theory (again, that I am aware of) that links the number of draws to any of the measures you've noted. In order to examine this systematically, I suggest you reduce the number of random parameters to 2 or 3 - the mix of normal and lognormal is also a substantial complication - and see if the same patterns emerge. Also, estimating covariances of unobservables is complicated, so you might want to examine this dimension.

I would like to perform a hybrid logit in Nlogit6. I used the syntax suggestions in Hensher et al., (Hensher, D., Rose, J., Greene, W., 2015. Applied Choice Analysis. A Primer, 2nd ed Cambridge University Press, New York.) but the instructions are fuzzy. Could you please send me a syntax example? Thank you in advance.

I am interested in incorporating some latent psychometric variables in the choice model, hence the hybrid specification. Thanks for responding.
