I was able to resolve my issue. I assumed my survival rates followed an exponential, so took the log of them and fit the resulting values to a linear model.
Would survreg allow me skip this step? I'm a newbie to the survival package so am not very familiar with its capabilities. -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Lancaster, Robert (Orbitz) Sent: Wednesday, October 26, 2011 1:40 PM To: r-help@r-project.org Subject: [R] survival: fitting equation to survival curve? Given a survfit object, is it possible to fit an equation to the resulting survival curve? Is this possible? What about with a coxph or survreg object?
