Congratz dude!! I think you will get into all of those that you have applied to..
My preferences are
1) Columbia(cuz it's 1 year only, 8 classes only. + east coast, close enough to wall street)
2) UCLA(already know the surroundings, it's 2 yrs, in-state tuition and it is easier to get switch over to Phd)
2) Michigan (have better rank, and I really likes the program in there, but 2 yrs outstate tuition is kinda...)
4) UCSD (I think their MS in Stat is a preparation for phd candidates)
5) Cornell(MPS? Heard it somewhere that the program is useless, but 1 year only)
Btw, you said the results are available in your online application,
and let's just say for UCLA, did you see it somewhere says that you were admitted? or you have to click on "Message Center" to find out? Because for the Stats here at UCLA, glenda(student affair) told me that I won't be able to hear back until/after April 1st. And my guesses are that the date is probably different with bio-stat.
Anyways, thanks again!
