R package for bootstrapping (comparing two quadratic regression models)
...els with non-parametric
bootstrap.
However, I do not know which R package can serve the purpose,
such as boot, rms, or bootstrap, DeltaR.
Please kindly advise and thank you.

The two quadratic regression models are
y1=a1x^2+b1x+c1
y1= observed migration distance of butterflies()
y2=a2x^2+b2x+c2
y2= predicted migration distance of butterflies (based on body mass)
x= body mass of butterflies
null hypothesis: a1=a2 and b1=b2 and c1=c2
bootstrap to test if the coeffients (a, b, c) of the y1 and the y2 model
differ

significant test of two quadratic regression models (lm)
Hello,
I am work with two quadratic regression models
y=ax^2+bx+c with the function of lm.
y1= observed migration distance of butterflies(y1=a1x^2+b1x+c1)
y2= predicted migration distance of butterflies (based on body mass)
(y2=a2x^2+b2x+c2)
x= body mass of butterflies
Now I would like to check the two regression model differ
by testing if the coeffients (a, b, c) of the y1 and the y2 model differ
(null hypothesis: a1=a2 and b1=b2 and c1=c2)
Please kindly advise any significant test in R for the purpose.
Also, please kindly...

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL
