similar to: parsing error when using R CMD check

Hi all, I have a dataset in which the output Y is observed on two groups of patients (treatment factor T with 2 levels). Every subject in each group is observed three times (not time points but just technical replication). I am interested in estimating the treatment effect and take into account the fact that I have repeated measurements for every subject. If I do this with repeated measures

Hi I got two questions about the nnet function in R. I would be thankful to have an answer. 1) Does the function intrinsically normalize the X and Y matrices before the training, or normalization should be done by the user. 2) I need to understand the $wts matrix. I do imagine that it is a single column transformation of the two matrices of weighs (input to hidden Ninputs+1 x Nodes) and

Hi everyone, I am trying to build a R library called nnNorm but I have some troubles checking and installing it. Here is the setup: If I don't use a inst\doc directory(with the vignettes files) in my source, the install step is working fine: C:\test>RCMD INSTALL nnNorm ---------- Making package nnNorm ------------ adding build stamp to DESCRIPTION installing R files installing

Hi everyone, According to R reference manual, the nnet function uses the BFGS method of optim to optimize the neural network parameters. I would like, when calling the function nnet to tell the optim function not to produce the tracing information on the progress of the optimization, or at least to reduce the frequency of the reports. I tried the following: a) nnet default > x<-rnorm(20)

Has the Levene test of homogeneity of variance been implemented in any library in R?

Dear list members, Where can I find code for computing the p*p variance-covariance matrix given a vector of p variances (ordered varA, varB, ..., varp) and a vector of all possible correlations (ordered corAB, corAC, ..., corp-1,p)? I know that the covariance between 2 variables is equal to the product of their correlation and their standard deviations: corAB * varA^.5 * varB^.5 and so:

Dear all, I often import data sets from other programs that contain user defined missing values. As an example consider a variable MXPLOCO with a user defined missing value of as -9. > summary(MXPLOCO) Min. 1st Qu. Median Mean 3rd Qu. Max. NA's -9.000 4.750 5.000 5.349 6.000 8.500 2.000 The following command successfully converts the value -9 to NA. However,

Hello all, I wanted to share with you this announcement for an upcoming workshop on the analysis of neural data to be held this summer at woods hole, MA. The workshop has been extremely productive in the past years and we anticipate another good working group this year. This workshop is applicable for any working in time series analysis whether it involves point processes or sampled continuous

For myself KSM is unpredictable feature. The problem is Compute, just this node does "copy on write" , so only Compute. My concern exactly is where would it lead to worse or better Guest behavior ? I am not expecting complete fix. I would track via top/htop and dmesg via Cron on 1-2 hr period. ________________________________ From: centos-virt-bounces at centos.org

Hello Xlord, The CPU does have VT support and I already have the nested KVM enabled. Checking the Linux Kernel release notes I saw that the nested kvm feature was implemented in 3.10 but he EPT support is in 3.12. So Centos 7's kernel which is 3.10 does have the EPT support? Is there a way to check that the EPT support is available in the kernel? Thank you, Laurentiu On Thu, Aug 4, 2016,
