<p>Does anybody know how many admits to Harvard are also admitted to Yale (ideally for '14)? I don't even know if the data exists, but I'd kind of like to hear what you guys have to say.</p>
<p>Such data are not available.</p>
<p>well, cross admit data says, with a 95% confidence interval, 54.8% to 71.1%. choose H. (Conversely, of course, 28.9% to 45.2% go Yale)</p>
<p>H received 30,500 aps with an admit rate of 6.9%
Y received 25,869 aps with an admit rate of 7.5%</p>
<p>So determining the cross admit pool size (within statistical parameters) should be trivial.</p>
<p>^ The school admit rates and school selection stats are independent. I don’t see how that shows the cross admit pool size. Can you show the trivial math I am missing?</p>
<p>^ditto 10char</p>
<p>Darn it, I was waiting for some stats whiz to chime in and do the ‘trivial’ math. Well, since the total # of Yale admits is 1940 and H is 2104, we can say with absolute certainty that the cross admit pool size is >=1, and <=1940, haha.
With the cross admit confidence interval stated 95% and the range of 16.3% (71.1-54.8), the sample size needed to arrive at that will be around 130…I think. Of course the sample size isn’t likely the same as the population size.
So, I’m going to throw all that out and use a nice Fibonacci ratio of 38% of the 1940 Yale admits and say 737 students are admitted to both. (range of 456 to 1018). (And I’m 80% certain of those numbers. :-)</p>
<p>I’ll agree to your statement that the cross admit pool is >=1 and <= 1940.</p>
<p>To complicate things further, the 7.5% for Yale was the April first admits, right? In other words, it would not take into account people like my daughter who was admitted to Harvard on April 1, but not admitted to Yale until she was taken off the waitlist on May 1. Technically she is still a cross-admit.</p>
<p>
Hilarious! hahaha</p>
<p>Here’s another way of estimating it: Every year, Harvard accepts about 500 people who choose to go elsewhere, and Yale accepts about 650 people who choose to go elsewhere. All indications are that the vast majority of those people at each school wind up going to the other, or to Stanford, Princeton, or MIT. (A few go to other colleges that give them prestigious full-ride merit scholarships, or to places like West Point or Deep Springs, but all of them together probably aren’t 10% of the people going elsewhere.) And I think all indications are that Harvard and Yale are each the modal destination for people who turn the other down. I think what that means (given the figures cited above) is that there are somewhere around 125-175 Harvard acceptees in each Yale class, and 200 (give or take) Yale acceptees in each Harvard class. </p>
<p>And, of course, some of the Harvard and Yale cross-admittees won’t go to either, because they will be at Princeton, Stanford, MIT, or one of the other choices. I am guessing that’s at least 20-25% of the cross-admit pool, maybe more.</p>
<p>So a cross-admit pool in the vicinity of 400-450.</p>
<p>Lots of assumptions here that are difficult to support with precision, but I think it’s a pretty good estimate.</p>
<p>65% in Harvard’s favour I believe. Very likely more.</p>
<p>Yeah, that sounds reasonable JHS…</p>

<p>Wow, JHS, I never thought of it that way. Thank you so much for that response!</p>
<p>For class of 2014, Stanford cross-admitted 398 with Harvard. I would guess there were more among HY.</p>
<p>Stanford cross-admitted 359 with Yale, 430 with Princeton, and 304 with MIT.</p>
<p>Where did you find that?</p>
