It is not homework. My problem is this: I used nonlinear regression to fit a
lognormal cumulative distribution to the probability of a buildings' collapse
against a measure of seismic intensity. I am able to obtain the asymptotic
confidence intervals. I am not , however, certain that they are

With difficulty!
There is far too little here to go on, and this seems an odd question
unless it is homework (why dictate a problem-strewn metho
How do you use bootstrap to estimate the confidence as well as the prediction
intervals in nonlinear regression ?

see that the predict.nls function has an interval argument, but a
previous post indicates that this argument has not been implemented.
Is this still true? I have tried various way

Much quicker than asking for help on the list is to read the help file
(which you have been asked to do in the posting guide you hopefully read).
?predict.nls tells us:

confidence interval on the mean responses are to be cal
