Dear All,
There are two packages which can be used for sensitivtiy analysis when the
predictor variables are correlated.
a: pcc (partial correlation coefficient) in R sensitivity package
b: varimp in R party package (conditional importance)
Are other R packages available for sensitivity anlaysi

Dear All,
Anyone has some idea how to implement 632 estimator and leave-one out
bootstraping method by using boot package. I know the bootstrap package has
this function, but it sounds not very flexible for my project.
Thanks,

Dear all,
The variable selection in regression is usually determined by the training data
using AIC or F value, such as stepAIC. Is there some R package that can
consider both the training and test dataset? For example, I have two separate
training data and test data. Firstly, a regression mode

Dear all,
I just try to run the example in R brugs packages, but not only once. Loop is
added in this example. After several times (7, 11, or other random number),
there is an error message "r for windows gui front-end has stopped working".
This happened in two laptops with windows 7 and vista.
Dear all,
I have a general relationship, which can be easily
solved using forward engineering model,
y=f(x1, x2, x3)
Now I know a distribution of y, how can I get the
corresponding distributions for x1, x2, and x3? In another situation, if I know
the distributions of y and x1, how can I ob

I have seen this outcome as well with graphs from time to time and
agree with Jean-Christophe that the bug seems to creep in at the

Hi all,
I copy metafile boxplot from R to Word. Then save as Pdf file. But I found

Please give me some advice how to get rid of these black lines in PDF files.
Thanks a lot,
Jim
