SEM standardized path coefficients
...All.S 0.4156191 1.0000000
But, conducting an SEM yields:
sem.mod = specifyModel('SEM_NDVI_AllS_model.txt')
sem.mod.cov = rawMoments(~ NDVI + All.S, data = df)
sem.mod.cov = sem.mod.cov[-1,-1]
sem.mod.cov
NDVI All.S
NDVI 0.7820657 13.53573
All.S 13.5357259 245.71360
sem1 = sem(sem.mod, sem.mod.cov, N=29)
stdCoef(sem1)
n2S n2S 0.97643950 All.S <--- NDVI
n2n n2n 1.00000000 NDVI <--> NDVI
s2S s2S 0.04656591 All.S <--> All.S
I am using version 3.0 of sem on R-14.0.
Thanks for any insight anyone can provide.

Another SEM question
Hello,
I use the function sem the following way
sem.mod <- sem(model, mod.cov, N=109) where the variables are modelled:
Z -> M
Z -> I
Z -> R
M <-> M
I <-> I
R <-> R
Z <-> Z
The output is

new version 2.0-0 of the sem package
Dear R users,
Jarrett Byrnes and I would like to announce version 2.0-0 of the sem package
for fitting observed- and latent-variable structural equation models. This
is a general reworking of the original sem package (which is still available
on R-Forge as package sem1).
Some highlights of sem 2.0-0 include:
o More convenient and compact model specification, including the default
automatic generation of error variances for endogenous variables and more
compact specification of error covariances. In the near future, we
anticipate releasing an update that permi...

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
