Confident interval for nls predictions
...nterval for the individual predicted Y. According to the stats text I looked at, I need to change the above formula to
se.fit<-sqrt(apply(gradient, 1, function(x)
sum(vcov(myNLSmodel)*outer(x,x))+NEWTERM))
where NEWTERM is
NEWTERM<-myNLSmodel$m$deviance()/(nObservations - nParameters)
So the problem is that while the confidence intervals are close to those provided by SAS, they are always smaller. This, in the end, makes a large difference for the application. Can anyone suggest how I might make the confidence intervals I calculate in R match up with those of SAS for nls?...

How to use mle or similar with integrate?
Hi
I have the following formula (I hope it is clear - if no, I can try to
do better the next time)
h(x, a, b) =
integral(0 to pi/2)
(
(
integral(D/sin(alpha) to Inf)
(
(
f(x, a, b)
)
dx
)
dalpha
)
and I want to do an mle with it.
I know how to use mle() and I also know about integrate(). My problem is
to give the parameter values a and b to the
