distributions are also possible to fit, e.g., the exponential (Weibull with shape = 1). Göran On Wed, Jan 23, 2008 at 5:46 PM, Beth Ireland [EMAIL PROTECTED] wrote: Dear All, I would like to fit some parametric survival models using left truncated, right censored data in R. However I am having

Bill Meeker's programs for reliability analysis can fit this, they are part of his SPLIDA package for Splus. I'm not sure that anyone has ported these to R however. The survreg routine does not handle this case, and psm call survreg to do the actual work. Terry Therneau

Dear All, I would like to fit some parametric survival models using left truncated, right censored data in R. However I am having problems finding a function to fit parametric survival models which can handle left truncated data. I have tested both the survreg function in package survival
