Johnson transformation
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 ____________________________________________________________ 6X velocizzare la tua navigazione a 56k? 6X Web Accelerator di Libero!

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 8 0.02

silhouette fuzzy
...isp silhouette index vector (si). Too it dependending on K=2,...,K.max=6; the result divided by the sum of these differences I need a final vector composed of the indexes for each clustering (K=2,...,K.max=6). There is a method, i think that is classe.memb, but i can't to solve problem because trasformation of the membership degrees matrix( (ris$membership) and of list object (ris$silinfo), does not permit me to use classe.memb propertyes. . ??(u?1-u?2)s?/??(u?1-u?2) > head(t(A.sort)) membership degrees table ordering by max to min value [,1] [,2] [,3] [,4] 1 0.66 0.30 0.04 0.01 2...

[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,...

[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 to make it work? Am I missing something or the...

explanation why RandomForest don't require a transformations (e.g. logarithmic) of variables
...s, 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. Some people could suggest me text or bibliography to study? thanks in advance Gianni [[alternative HTML version deleted]]
