[R] SURVREG Function

Hi, I need some help to manage frailty in Survreg function; in particular I'm looking for more information about frailty in survreg function applied to a loglogistic hazard function. Actually I need to develope a predictor for frailty random variable realization (similar to the Proportional

Re: [R] Survreg function for loglogistic hazard estimation

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 -- View this message in context:

[R] survreg function in survival package

Hi, Is it normal to get intercept in the list of covariates in the output of survreg function with standard error, z, p.value etc? Does it mean that intercept was fitted with the covariates? Does Value column represent coefficients or some thing else? Regards,

[R] Survreg function + deviation

I am trying to estimate by MLE weibull coefficients and deviation. But how can i estimate deviation? I tried to find at the list and at the internet this but couldn't make it. Anyone could help me on this? Thanks. [[alternative HTML version deleted]]
