Dear Victoria,

shared(varname) is described as shared frailty ID variable in Stata 12.1
manual under -streg- entry (p 359).

Otherwise, see command -streg- Model 2 that leads you to the Shared frailty
ID variable option.

Best regards,
Carlo

Oggetto: st: Paramertric survival analysis: shared frailty

I conducting a survival analysis and wish to model hospital-level effects.
Using "stcox", there is an option to estimate the random effects
"effect(nu)", however this option is not allowed with the "streg" command
for parametric survival analysis. I wish to know if there is an option
equivalent to "effects(nu)" that can be used with "streg", or alternatively
how else I can get an estimate the random effects?

Kind Regards

Victoria Allan
