confidence / prediction ellipse
...lot.
>From what i understood the ellipse() function return an ellipse based
parameters: shape, center, radius .
If i read dataEllipse() function i can see how these parameters are
calculated for a confidence ellipse.
ibrary(car)
a=c(12,12,4,5,63,63,23)
b=c(13,15,7,10,73,83,43)
v <- cov.trob(cbind(a, b))
shape <- v$cov
center <- v$center
radius <- sqrt(2 * qf(0.95, 2, length(a) - 1)) # radius <- sqrt(dfn *
qf(level, dfn, dfd))
conf.elip = ellipse(center, shape, radius,draw = F)
plot(conf.elip, type='l')
points(a,b)
My question is how I can calculate shape, cent...

Idmap_rid differs on FreeBSD and SLES!
...and GID:s.
All the FreeBSD servers are getting the same ID:s but the SLES are
getting it's own.
I'm using:
idmap backend = idmap_rid:DOM1=10000-20000
idmap uid = 10000-20000
idmap gid = 10000-20000
That setting are the same on all servers!
Any clues out there?
Thanks for your time!

Fit elipse to xy scatter
Hi,
I know there is a package 'elipse' available but I'm not sure how to use it
for my specific implementation.
What I would like to do is fit an elipse to two lines of identity (at right
angles to each other), as indicated in the following figure:

Conceptually, I'm really struggling to even come up with a way of
