I am running my code in a loop and it does not work but when I run it outside the loop I get the values I want. n <- 1000; # Sample size fitglm <- function(sigma,tau){ x <- rnorm(n,0,sigma) intercept <- 0 beta <- 0 ystar <- intercept+beta*x z <- rbinom(n,1,plogis(ystar)) xerr <- x + rnorm(n,0,tau) model<-glm(z ~ xerr, family=binomial(logit))

------------------- Version 2 of my problem improving the definition of what the optimal solution would be. Dear all, I'm working on the following problem: Assume two datasets: Y, Y that represent the same physical quantity Q. Dataset X contains values of Q after an event A while dataset Y contains values of Q after an event B. In R X, Y are vectors of the same length, containing

I am new to R and I am trying to do a monte carlo simulation where I generate data and interject error then test various cut points; however, my output was garbage (at x equal zero, I did not get .50) I am basically testing the performance of classifiers. Here is the code: n <- 1000; # Sample size fitglm <- function(sigma,tau){ x <- rnorm(n,0,sigma) intercept <- 0 beta

Updating gnulib has caused -Wformat-signedness to be enabled. This has revealed many problems in C format strings. The fixes here fall into the following main categories: - Using %d with an unsigned parameter. - %x and %o expect an unsigned argument. - uid_t and gid_t are unsigned on Linux. The safe way to print these is to cast them to uintmax_t and then print then using the %ju

Hello, I would like to try to edit/modify default values of winebrowser.exe (for example with Reshacker) for it to open url and email addresses with Seamonkey...

Forgot to specify that the cross-val error cannot be decreased lower than 0.91. Note that for smaller values of cp than 0.01, the cross-val error increases. Is the cross-val error sum of squared error or relative error for classification problem (method = "class" in rpart function) or another type of error? Is it possible to determine the true positive, false positive using rpart?

Dear all, I'm working on the following problem: Assume two datasets: Y, Y that represent the same physical quantity Q. Dataset X contains values of Q after an event A while dataset Y contains values of Q after an event B. In R X, Y are vectors of the same length, containing effectivelly a number of observations of Q in each state. Q is a continous variable. Now, the two datasets should

Instead of generating the p2v kernel config using the OCaml generator, create a Perl script to do this job, mostly at build time. This is done to rely less on the generator for p2v, and because the generation of these sources is quick enough that it can be done at build time (instead of shipping the generated sources in dist tarballs). The generate-p2v-config.pl mimics what

As preliminary steps in splitting virt-p2v to an own repository, start making p2v more independent within libguestfs. This is accomplished by the following changes: - generate the p2v kernel config sources & docs at build time using a Perl script, rather than the generator (so no need for OCaml when building from git, and no generated sources in dist tarballs) - create two local test

It should be very compatible with the Perl version. --- .gitignore | 3 + Makefile.am | 2 +- configure.ac | 1 + make-fs/Makefile.am | 82 +++++ make-fs/make-fs.c | 736 +++++++++++++++++++++++++++++++++++++++++++ make-fs/test-virt-make-fs.sh | 96 ++++++ make-fs/virt-make-fs.pod | 252 +++++++++++++++ po/POTFILES

I thought it would be easy to rewrite virt-make-fs in C. Two days later ... The Perl program uses a lot of external commands, which makes it pretty tedious to implement in C. Rich.

Hi, this series update libguestfs to a recent gnulib version, so that we can use its new getprogname module, and solve altogether one of the porting issues (the need for 'program_name' by the error module of gnulib), and have a single way to get the name of the current program. A number of changes in tools mostly, although mechanical. Thanks, Pino Toscano (3): Update gnulib to latest

These are a prelude to fixing https://bugzilla.redhat.com/show_bug.cgi?id=1590220 A lot of the virt-p2v configuration code was duplicated manually. These changes make sure that most of it is generated. Rich.

Only in end-user messages and documentation. This change was done mostly mechanically using the Perl script attached below. I also changed don't -> don’t etc and made some other simple fixes.

libguestfs has used double and triple underscores in identifiers. These aren't valid for global names in C++. (http://stackoverflow.com/a/228797) These large but completely mechanical patches change the illegal identifiers to legal ones. Rich.

Now that virt-p2v has its own repository [1] and releases [2], it is time to remove it from libguestfs.
