alh - Just sharing my own experiences. I think it’s always interesting to compare notes and to see how different everyone’s perceptions are. I don’t know about you, but sometimes when I read the posts here I wonder if some people went to college in the same century I did !
I think CF answered your question about status in post #270. That is the precise definition of status that he uses, based on surveying male Greeks. You think it’s hard to get consensus on the tiering of sororities by status, and that’s fair. But Hernandez doesn’t worry about that. He’s very happy with averaging male Greek’s opinions. (I think it’s probably fine - the real improvement I would make is instead of having the statuses be simply 1,2,3,4,5,6,7,8,9; I’d incorporate the notion that sorority #1 and #2 may have roughly the same status but both are clearly of much higher status than sorority #3).
So I think you’re also asking another question - why then is Hernandez is collecting all this other status related data and discussing the algorithms for extending bids?
(I don’t know what kind of background you have in this stuff . You seem to be affiliated with a university - are you faculty / staff / administration in a related field? Apologies if I’m saying stuff you already know.)
Here’s why Hernandez is worrying about this. The question he wants to answer is to what extent does the status of a woman’s sorority influence the quantity of sex she supplies (that sounds vulgar !). But the problem is that high-status houses may be selecting women who are thinner / more attractive, which is a personal characteristic, not a characteristic of the sorority, So the status of a woman’s sorority isn’t a pure “exogenous” variable. And this may be driving why the girls hookup more, not the status of the sorority. This messes up his analysis since he can’t figure out the part that’s due to a sorority’s status and the part that’s due to the fact that they have more attractive members.
So he’s looking at the algorithms / data to try to find some variable (an “instrumental variable”) which influences which sorority a girl is in but doesn’t directly influence the number of hookups she has. For example, the amount of dues might be one - a girl’s budget could dictate what house she joins but wouldn’t influence the number of hookups she has (assuming that she can still buy the right clothes, makeup, etc.). This would enable him to fix his regressions.
However, Hernandez ultimately doesn’t use variables like “dues” to fix his regressions even though he suspects he should. But that’s ok - this is a classroom exercise and his adviser is probably satisfied that he’s shown he’s aware of the issue and has found a possible instrumental variable.
