Hi all,
 
I've got a list (Reg3Lst) with 1000 nls regression results in it.
I'd like to get the confidence interval of the parameters obtained with the
nonlinear regressions. Thus I've used this:
 
for (i in 1:1000) 
    {
    foo<-list(foo,confint(Reg3Lst[[i]]))
     }
 
For some regressions the confidence interval is not estimated because of a
singular gradient result. Then it stops the loop.
Is that possible to continue the loop after an error returned by confint?

 

Regards/Cordialement
