similar to: best subset selection on random effects model

Hi Pros, I know leaps() computes the best subset selection for linear model, and the bestglm() computes the best subset selection for generalized linear model. Is there any package for best subset selection on random effects model, or mixed effects model? Thank you so much. -- View this message in context:

I recently found the "bestglm" package while trolling CRAN for a function to save some keystrokes with simple (k<10) nested models. I am interested in using the best of several nested linear models which I have explored using lm(), glm() and now bestglm(). When I compare the AIC values for the 'best' candidate model I get the same AIC values with lm() and glm() but a

Hi all, I have been trying to run a bestglm in R for a while now and am struggling to get it to run. When I thought I had succeeded, the "output" it gave me was "NULL" and that's it. Below is my code: bestglmtest<-read.table("C:\\Documents and Settings\\clyons\\Desktop\\bestglmtest.txt",header=T,row.names=1) > names(bestglmtest) [1] "acc"

Hi all, I'm doing Multiple linear regression for a data set. However, it takes a lot of time, as I would like to check every possible combination of factors, evalute the results based for instance on their p values, and then choose the best regression model. So, I wonder if anyone might have a script for that? Or if not, do you have some suggestions how to create such a script? I've

Dear All, Suppose that you are trying to create a binary logistic model by trying different combinations of predictors. Has R got an automatic way of doing this, i.e., is there some way of automatically generating different tentative models and checking their corresponding AIC value? If so, could you please direct me to an example? Thanks in advance, Paul

Hi, I've been playing around with the APFloat class lately and I came across behavior I was not expecting based on reading the implementation comments and I'm wondering if it's a bug or intentional. The behavior concerns converting an APFloat to a string and back again. In the implementation of ``APFloat::toString(...)`` you can specify ``FormatPrecision`` as 0. The method comments

Hello - I have a population of 100 individuals that I would like to bootstrap 10 times, every time removing 5 *different* individuals. So far, I have done the following: pop <- read.table('mypop.txt', header=FALSE) replicate(10, sample(pop, 95, replace=FALSE)) I have not actually gone through each of the 10 files created to make sure no single individual was removed more than once

Hi; It seems to me that has probably been asked in the past. But I cannot find the track. I usually need to extract elements from a list and contruct vector from them; e.g., to create a table. Perhaps there is a way to directly extract them without looping? Simple example: > S.lst $sublist.1 $sublist.1$age [1] 24.58719 $sublist.1$weight [1] 60.82861 $sublist.2 $sublist.2$age [1] 32.39551

Hi ALL I have a question about DISK space of OCFS2. I copy a file by a "cp" command after check the DISK space by "df -k" command. There is no change when I cheked the DISK space by "df -k"command again. I show below an procedure. ------------------------------------------------------------------------------- root at CPU_N:/fm/bbb> ls -l total 3 -rwxr-xr-x 1

Hello R-ologists, Imagine you have a list "list" like so: >list [[1]] [1] "IPI00776145.1" "IPI00776187.1" [[2]] [1] "Something" "IPI00807764.1" "IPI00807887.1" [[3]] [1] "IPI00807764.1" [[4]] [1] "Somethingelse" What I need to achieve is a filtered list "list2" like so: >list2 [[1]] [1]

Hello everyone, I need some help with lists inside lists (a good way to emulate a struct)\ Assume that there is a small list called fred: fred <- list(happy = 1:10, name = "squash") and a big list called bigfred that includes fred list 5 times bigfred <- rep(fred,5) Is it possible somehow to index all these sublists(fred) inside bigfred with a more direct way like this:

Hi all, I am trying to extend a FunctionType to include new parameters. In particular, I want to ensure that the main function has been declared with both argsc and argsv. However there seems to be no easy way to accomplish this: llvm::Function::getFunctionType() returns a a reference to a const object, while modifying only the argument list yields an error during verification since the

Dear All, I need your help urgently I have to copy the CFG of each function using CloneFunction or CloneFunctionInto. After I made the copy function. Print the basic blocks then get this error : While deleting: i32 % Use still stuck around after Def is destroyed: %mul2_ = mul nsw i32 %6, 3 Use still stuck around after Def is destroyed: store i32 3, i32* %x_, align 4 opt: Value.cpp:75: virtual

Hi, i was looking through the docs and couldn''t find a good clean solution for ordering a partial with an :order clause. say i was iterating over categories and thier corresponding sub-categories (regular belongs to) and wanted to order the subcategories according to a certain column; <% for category in @categories %> <% render: partial => ''sublist'',

my problem is more complex than below but I think below can suffice. i have a list and the name of it at the top level is GGG. so, if i do an lapply and operate on lower components in the sublist, then I can do as shown in EXAMPLE 1 and what will come back will be named GGG at the top level. but, suppose that , the function inside the lapply function was more complex and i wanted to

Hi everyone, Suppose I have a list named "lst", see below: > lst $sub1 ... $sub1$x ... $sub1$y .... $sub2 ... $sub2$x ... $sub2$y ? $sub3 ... ... ... Now, I want to extract the sub-sublist $y from every sublist(sub1, sub2...) and then storage them to a new list. I know how to extract them by subscript or list name one by one, but I wonder if there exist some tricks to finish this
