An = number of units of alcohol consumed
S = smokiness of the room (graded from 0-10, where 0 clear air; 10 extremely smoky)
L = luminance of 'person of interest' (candelas per square metre; typically 1 pitch black; 150 as seen in normal room lighting)
Vo = Snellen visual acuity (6/6 normal; 6/12 just meets driving standard)
d = distance from 'person of interest' (metres; 0.5 to 3 metres)

Good to see those PhDs being put to good use!

I don't think it's right though, as S, L, Vo and d would have an effect, but if An = 0, the beer-goggle effect is 0, which would mean that the alcohol is required for the others to take effect.

Well that doesn't necessarily mean its incorrect, it just might only be valid for An > 0, since they are investigating the "beer goggle effect" they assume you are drinking.

I'm wondering what the sigma function is though?

Sounds right to me because without beer there should be NO beer-goggle effect, which doesn't rule out other things still effecting one's affection, so to speak. ;)
