The 2014 rankings of US statistics doctoral programs compiled by the U.S. News & World Report lists a few of the schools twice. I assume that the rankings are probably for different types of statistics programs (Harvard for example has both a statistics department but also a very good School of Public Health, which I'm sure has a biostatistics program), but the methodology section does not address this problem and I am doing research which requires analysis of this list.
Question: Why are some schools listed twice in the rankings?
I cannot request this information from U.S. News & World Report directly because they only release this information to university officials.
