I a trying to use survreg to fit a Weibull distribution. From the last few
messages I understand how to interpret the parameters. However, how do I get
the covariance of lambda and alpha? Is there a predict command for that?
Thanks

Dear Terry,
Thanks a lot for your reply. The result of survreg reads like:
Call:
survreg(formula = Surv(end, status) ~ fico_demean, data = raw,
dist = "loglogistic", model = TRUE)
Value Std. Error z p
(Intercept) 2.98365 1.34e-03 2233.2 0.00e+00
