distributions are also possible to fit,
e.g., the exponential (Weibull with shape = 1).

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.

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
