Hello,
I'm Carla, an italian student, I'm looking for a package to transform non normal data to normality. I tried to use Box Cox, but it's not ok. There is a package to use Johnson families' transormation? Can you give me any suggestions to find free software as R that use this trasform?
Thank yuo very much
Carla

clustering fuzzy
hello,
i'm pete ,how can i order rows of matrix by max to min value?
I have a matrix of membership degrees, with 82 (i) rows and K coloumns, K
are clusters.
I need first and second largest elements of the i-th row.
for example
1 0.66 0.04 0.01 0.30
2 0.02 0.89 0.09 0.00
3 0.06 0.92 0.01 0.01
4 0.07 0.71 0.21 0.01
5 0.10 0.85 0.04 0.01
6 0.91 0.04 0.02 0.02
7 0.00 0.01 0.98 0.00

[LLVMdev] type promotion i16 -> i32
...#39;m developing a llvm backend. It seems that, if i16 is not a legal type
(no register can hold i16 types in RegisterInfo.td and as a RegisterClass in
SelLowering.cpp), i16 should be promoted to i32.
Nonotheless, this simple program:
int main(){
volatile short a;
a= 3;
return 0;
}
which is trasformed in this IR:
define i32 @main() nounwind readnone {
entry:
%a = alloca i16, align 2 ; <i16*> [#uses=1]
volatile store i16 3, i16* %a, align 2
ret i32 0
}
fails to compile with the following error:
LLVM ERROR: Cannot yet select: 0x181c2d0: ch = store 0x1204a08, 0...

[LLVMdev] llvm passes under xcode
Hi, I am interested in developing some passes using the Xcode IDE.
I create a pass directory with a simple pass in it, add it to the
lib/Trasform/ directory, changed and added some CMakeList.txt files and
compiled using cmake (cmake -G Xcode).
The compilation gives me no errors but then I've found that I have not a
Debug+Asserts folder and opt has no option related to my pass...what can I
do

data.frame to shape
Hi all,
I have a simple question:
I have a data.frame like this:
id x y

10 74 1646895 4815264
11 74 1646762 4815513
and I'd like to trasform it with the "convert.to.shapefile"

explanation why RandomForest don't require a transformations (e.g. logarithmic) of variables
Dear Researches,
sorry for the easy and common question. I am trying to justify the idea of
RandomForest don't require a transformations (e.g. logarithmic) of
variables, comparing this non parametrics method with e.g. the linear
regressions. In leteruature to study my phenomena i need to apply a
logarithmic trasformation to describe my model, but i found RF don't
required this approach.

XML Databinding frameworks
Are there any XML databinding frameworks available for Ruby / Rails, such as
Castor or JaXB for Java?
Also are there framework such as Apache Axis for WebServices for Rails or
Ruby?

density estimation on 2-D bounded domain
Dear R experts,
density estimation on a 2 dimensional bounded domain
---------------------------------------------------------------------
I am currently trying to estimate the probability
density (PD) of cancers within the breast using
the sm library with the routine
sm.density
Of course a practical PD must be limited by the curve of the breast
outline.
I don't have a clue after perusing
