> Hello,
>
> I'm running R 1.8.1 on a Mac G4 with Dual 800 MHz CPU, 1.5 GB RAM, and
> sufficient disk space.
>
> I have loaded the boot package version 1.2-15.
>
> I defined a function to pass to the statistic argument which estimates
> a vector (length = 6) of parameter estimates; none are variances.
>
> I defined a function to pass to the ran.gen argument for parametric
> resampling.
>
> I created a boot object with R = 10000; the boot object appears to
> have the appropriate components of a parametric bootstrap object.
>
> When I pass the boot object to the boot.ci function I can get CIs of
> types = norm, basic, and perc on each parameter estimate.
>
> However, bca CIs are not returned and there is the following error
> message:
>
> Error in empinf(boot.out, index = index, t = t.o, ...) :
> Influence values cannot be found from a parametric bootstrap
>
> To knowledge I should be able to get bca CIs on a parametric bootstrap
> object.

> Any suggestions?
