Hi,
Sorry to bump an old thread, but I'm in a similar predicament as well. I also got an offer from arguably the top biostats PhD program but have another offer from a second tier stats PhD programs that is strong for interdisciplinary work. I'm generally interested in biological applications, so in that sense both would be a good fit, but I would maybe like to explore other areas as well. The recent academic placements are arguably better at the stats school, but it is hard to say whether this trend would continue. However, the biostats program seems to have stronger private sector placement. I am having a tough time deciding, so I would greatly appreciate hearing everyone's thoughts.
