similar to: MICE for Cox model

I am working with some survival data with missing values. I am using the mice package to do multiple imputation. I have found code in this thread which handles pooling of the MI results: https://stat.ethz.ch/pipermail/r-help/2007-May/132180.html Now I would like to plot a survival curve using the pooled results. Here is a reproducible example: require(survival) require(mice) set.seed(2) dt

Hi everyone, Does anyone here has experience using MICE to impute missing value? I am having problem to pool the imputed dataset for a MANOVA test, could you give me some advice please? Here is my code: > library(mice) >

Hello folks, I am a relatively new user of R and created multiply imputed data sets with the 'mice' library. This library provides two functions for complete-data analysis on multiply imputed data set objects (lm.mids and glm.mids). I am trying to estimate a series of Cox PH regression models and cannot figure out the best way to do this. Is it possible with the mitools library?

R-helpers: I am using R 2.5 on Windows XP, packages all up to date. I have run into an issue with the MIcombine function of the mitools package that I hoped some of you might be able to help with. I will work through a reproducible example to demonstrate the issue. First, make a dataset from the pbc dataset in the survival package --------------- # Make a dataset library(survival) d <-

Dear All, I'm trying to track down a problem with my quantreg package reported by a user doing censored quantile regression. When he runs the test4.R file attached below (which reads the csv file also attached) on his windows machine he gets an error like this: > Error in dimnames(B) <- list(c("tau", dimnames(x)[[2]], "Qhat"), NULL) : > length of

Hi, I am relatively new to R; when creating functions, I run into problems with missing values. I would like my functions to ignore rows with missing values for arguments of my function) in the analysis (as for example is the case in STATA). Note that I don't want my function to drop rows if there are missing arguments elsewhere in a row, ie for variables that are not arguments of my

Dear list, I have problems involving passing a "subset=" argument through "...". I'm trying to augment the set of defined analyses for mice (homonymous package) with a call to lme. This package create multiple imputations of missing data in a "mids" object, each completed data set may be obtained through the complete(data, set) function. > sessionInfo() R

I am working on a two stage threshold quantile regression model in R, and my aim is to estimate the threshold of the reduced-form equation (call it rhohat), and the threshold of the structural equation (call it qhat), in two stages. On the first stage, i estimate rhohat by quantile regression and obtain the fitted values. I use these fitted values to estimate qhat on the second stage. The code is

Hi, I'm reading van Belle et al "Biostatistics" and trying to run a cox test using a dataset from: http://faculty.washington.edu/~heagerty/Books/Biostatistics/chapter16.html (Primary Biliary Cirrhosis data link at top of the page), I'm using the following code: --------------- start of code library(survival) liver <-

Hi, I used to use reshape and moved to reshape2 (R 2.15.1). Now I tried some of my older scripts and was surprised that my cast function wasn't working like before. What I did/want to do: 1) Melt a dataframe based on a vector specifying column names as measure.vars. Thats working so far: dfm <- melt(df, measure.vars=n, variable_name = "species", na.rm = FALSE) 2) Recast the

Hello, While working on a fix for the rare-but-possible problem of reentrant NMIs and MCEs, I have discovered that it is sadly possible to generate fake NMIs and MCEs which will run the relevant handlers on the relevant stacks, without invoking any of the other CPU logic for these special interrupts. A fake NMI can be generated by a processor in PIC mode as opposed to Virtual wire mode, with a

I read in a CSV file with Data <- read.csv(file="FileName.csv",head=TRUE,sep=",") the file containts strings in the 2nd and 3rd columns and each has about 1000 rows. I need to either loop through the strings there looking for strings that would trigger other logic or remove those rows and put them in another array and loop through them in the new array. I can't seem

Well, depends on how you want to see it. Under SEV-ES an IRET will not re-open the NMI window, but the guest has to tell the hypervisor explicitly when it is ready to receive new NMIs via the NMI_COMPLETE message. NMIs stay

I'm trying to create a language structure that is a call to a function with a number of arguments that is only known at run time. I do this by using repeated indices to expand out a call with a single argument. However, when I change one of the arguments, all are changed. I don't see the same behavior when I initially create a call with multiple arguments. Even more strangely,

The self_nmi() code cause''s an NMI to be triggered by sending an APIC message to the local processor. However, NMIs are blocked by the VMEXIT, until the next iret or VMENTER. Volume 3 Chapter 27 Section 1 of the Intel SDM states: An NMI causes subsequent NMIs to be blocked, but only after the VM exit completes. As a result, as soon as the VMENTER happens, an immediate VMEXIT happens

I tried to compile this snippet of C++ code: void FuncTest() {     int* a = new int;     int* b = new int[2]; } using: clang test.cpp -S -emit-llvm -o - > test.llvm and obtained this: define void @_Z8FuncTestv() { entry:   %a = alloca i32*, align 4   %b = alloca i32*, align 4   %call = call noalias i8* @_Znwj(i32 4)   %0 = bitcast i8* %call to i32*   store i32* %0, i32** %a, align 4  

Thanks. isFreeCall() works well but for %call2 = call i32 bitcast (i32 (...)* @free to i32 (i8*)*)(i8* %call1) nounwind, !dbg !16 So I tried to figure out when the above instruction occurred. When <stdlib.h> is included, free(buf2R1); turn into call void @free(i8* %call1) nounwind, !dbg !16 when I forget to include <stdlib.h>, free(buf2R1); turn into %call2 = call i32 bitcast (i32

This patch is overcomplicated IMO. Just do the magic incantation in C from do_nmi or from here: /* * For ease of testing, unmask
