How do you interpret this? Do I still have a chance for funding? This is a top 50 school (excluding Biostatistics), top 70 if including Biostatistics. Do highly-qualified students usually reject offers from this tier of schools?
You were one of the top applicants to whom no assistantship was offered, though, so there remains a chance, as offers are turned down, that a position could open up for you. We would probably not know this until mid-April, and we will inform you if such a situation arises.
