Getting the Bootstrap Error Rate of QDA
...tructure(data.matrix(x), class = "matrix"), ...) :
Rank deficiency in group M
with my qda.bootstrap() looks something like:
> qda.bootstrap <- function(data, index) {
+ boot.qda <- qda(x = data[index, 2:9], group = data[index, 1])
+ qda.pred <- predict(boot.qda)
+ boot.resub <- sum(qda.pred$class != data[, 1]) / nrow(data)
+ data.pred <- predict(boot.qda, data[, 2:9])
+ data.resub <- sum(data.pred$class != data[,1]) / nrow(data)
+ abs(data.resub - boot.resub)
+ }
If I run qda.boot <- boot(train, qda.bootstrap, R = 500) a couple of
times, it sometime...

Bootstrap error rate of logistic disrmination model
...ting probabilities instead
of group allocation as for lda(). In that case maybe someone knows of a
function which predicts goup allocations for data in a logistic reggression
that i can use.

boot.df=lda(x=white[index,4:6],group=white[index,3])
boot.pr=predict(boot.df)
boot.resub=sum(boot.pr$class!=white[index,3])/nrow(white)
data.pr=predict(boot.df,white[,4:6])
data.resub=sum(data.pr$class!=white[,3])/nrow(white)
bias=data.resub-boot.resub
bias
}

I realise doing this bootstrap could be very time intensive for the computer

What happened to my subscription?
I haven't received any messages after 3/27/06 and I have tried to resub
twice without any success?
I miss the flood of messages, and I have other stupid questions to ask
;~)

macaddress blacklist problem
I helped set up a firewall at my brother''s church and we are running
shorewall 1.4.6b on a redhat 9 box. Works well.
[root@fumcbafw shorewall]# uname -r
2.4.20-19.9
[root@fumcbafw shorewall]# iptables --version
iptables v1.2.7a
The box also serves as a dhcp server for the church offices and there is
one box that apparently still has the old firewall config (zone alarm)
on it since it

how to update solaris packages without keeping local copies
Greetings,
I have a solaris package stored on a puppet server. I''d like
to be able to maintain the package on a client system without
having to also keep a copy of the package file on the client
system. (think lots and lots of packages)
Checksums work okay for noticing changes on the fileserver,
but it seems that I have to keep a local copy of the file as well.
When I rev the package
