performance question
Hi,
I am about to write functions for multivariate kernel densitiy estimation
with mixed categorical and continuous date (accoring to Jeff Racine and Qi
Li), and the leave-one-out window esitmation needs a lot of computation.
I am now optimizing the code performance and therefore fhe following
questions:
As R uses call-by-value for functions, is it computational expensive to pass
large matrices

hello
for exampl, i have this programme
# Generating data which are right truncated
library(DTDA)
library(splines)
library(survival)
n<-25
X<-runif(n,0,1)
V<-runif(n,0.75,1)
for (i in 1:n){
while (X[i]>V[i]){
X[i]<-runif(1,0,1)
V[i]<-runif(1,0.75,1)
}}
res<-lynden(X=X,U=NA, V=V, boot=TRUE)
attach(res)
temps = time
M_i = n.event
L_t = res

Three-way Panel Data Analysis
Dear R users,
I have panel data on the amount of money spent by travellers from 8 origin
countries in 4 destinations. I would like to carry out analysis for
destinations, origins and time. However, it seems to me that the package
"plm" can only esitmate two-way panel data (indexed by a two-dimensional
array). Any suggestions would be greatly appreciated.
Thank you.
Best regards,
Danice

Extract information from the summary of 'lm'
...Coefficients:
Estimate Std. Error t value Pr(>|t|)
(Intercept) -1.7782 0.5948 -2.990 0.004879 **
x_var 2.1237 0.5073 4.187 0.000162 ***
---
Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.'
0.1 ' ' 1
I can get the esitmates (i.e. -1.7782 and 2.1237) of
coefficients by calling
results$coefficients
But I don't know how to get the corresponding t values
and P values for those coefficients. I am running a
lot of regression models and I can not run 'summary'
every time to get the t and P values for each mode...

X-fold cross validation function for discriminant analysis
Hi all,
I ran a discriminant analysis with some data and want to get a general idea
of prediction error rate. Some have suggested using X-fold cross validation
procedure. Anyone know if there is a function for this in R?
Thanks,
Wade

[OT] Just saying hi!
I hope this list is small enough for not beeing banned when
introducing oneself. So...
Hi,
I just subscribed to the theora-lists. I'm from the XVID project,
so I know a deal about video and MPEG-4 in particular, but nothing about
Vorbis/Theora etc., That's why I'm here, because I'm interested in
patent-free alternatives.
I guess there is no documentation of the current status
