    • Medulloblastoma Problem File

      This is a problem on length- and lead-time bias that we were going to put on PSet#8, but it's too hard and requires a lot of clinical knowledge.   I tried to add some explanation and some additional pieces to make it easier.  Martina and Tom are planning to discuss it at large group discussion.   They have not reviewed my changes and may think I made things worse rather than better.
