| This is a page where I am noting resources, as I come across them, 
              for my own and my students' use.  Sources of online information 
              on   
              Statistical methods  
                various

                      Cox 
                    Proportional Hazards Survival Regression (John C. Pezzullo,

                    of Washington, lecture in BIOST 515, Introduction to regression 
                    models). Lecture bullets, but detailed. Requires some 
                    comfort with math. (link) Chapter
