True. I can't tell you what *the* sufficient N is. Maybe you'll find
some simulation studies on the topic in statistical journals. My
personal rule is not to use logit if N<100 (and I'd be suspiciuos if
N<500). However: As you mentioned, this all strongly depends on model
complexity and distributional characteristics...
