Dear R Users on a self-written function for calculating maximum likelihood probability (plz check function code at the bottom of this message), one value, wden, suddenly jump to zero. detail info as following: w[11]=2.14 lnw =2.37 2.90 3.76 ... regw =1.96 1.77 1.82 .... wden=0.182 0.178 0.179... w[11]=2.14 lnw=2.37 2.90 3.76 ... regw =1.96 1.77 1.82 .... wden=0.182

Hey, R users I do not know how to describe my question. I am a new user for R and write the following?code for a dynamic labor economics?model and use OPTIM to get optimizations and parameter values. the following code does not work due to the?equation: ?? wden[,i]<-dnorm((1-regw[,i])/w[5])/w[5] where w[5]?is one of the parameters (together with vector a, b and other elements in vector

Hi everyone. I have a problem that I have been unable to determine either the best way to proceed and why the methods I'm trying to use sometimes fail. I'm using the pf() function in an optimization function to find a noncentrality parameter that leads to a specific value at a specified quantile. My goal is to have a general function that returns the noncentrality parameter that

Dear helpers, I am using R version 2.5.1 to estimate a multinomial logit model using my own maximum likelihood function (I work with share data and the default function of R cannot deal with that). However, the computer (I have an Athlon XP 3200+ with 512 GB ram) takes quite a while to estimate the model. With 3 categories, 5 explanatory variables and roughly 5000 observations it takes 2-3 min.

All the LLVM lab FNT builders were reporting failures in the same set of tests (scimark2, LivermooreLoops, some others). Now they've all turned green but the same tests are still failing. I don't see any commits to deliberately make the FNT pass, so it looks like someone broke failure detection... Note that the FNT "report" text became empty at the same time. Here's what

This issue is back: FNT bots are reporting success in spite of tests failing, and the "report" text is empty again. Did someone change something? Ciao, Duncan.

Hello everyone, It might make sense to start from rebooting the buildmaster, just to make sure everything is all right on this end. Yesterday I have tried to apply the latest changes from zorg and some of them are broken. Theoretically, checkconfig shouldn't affect the working instance, but the reality could be different... I planned to rollback to the last known-to-be-good revision and

All, This buildbot is getting lots of assertion failures in the test suite. They were probably caused by my commit: ------------------------------------------------------------------------ r151049 | foad | 2012-02-21 09:25:52 +0000 (Tue, 21 Feb 2012) | 6 lines Changed paths: M /llvm/trunk/lib/VMCore/LLVMContextImpl.h M /llvm/trunk/lib/VMCore/Type.cpp PR1210: make uniquing of struct and

Dear R list members, I have a question about the proper use of the typsize and fscale arguments to nlm. I use nlm in my sem package to fit general structural-equation models, which entails maximizing a multinormal likelihood with respect to parameters that represent regression coefficients and covariances of variables. The magnitudes of these parameters can be very different. The

It would be really nice if nlm took a set of "..." optional arguments that were passed through to the objective function. This level of hacking is probably slightly beyond me: is there a reason it would be technically difficult/inefficient? (I have a vague memory that it used to work this way either in S-PLUS or in some previous version of R, but I could easily be wrong.) Here's

Hi all, after inserting another sieve-rule, I get the following backtrace on deliver. The mail gets delivered into the Mailbox, but as deliver does not exit with 0, postfix bounces the mail.

Hi I'm running the nightly test suite locally and getting a difference with the output from this buildbot (http://lab.llvm.org:8011/builders/clang-x86_64-debian-fnt/builds/1168/steps/make.test-suite/logs/stdio) For .ll tests the buildbot does the following (look for spirit.cpp in that link. Only comes up twice, one of which is this one)

Dear R community, I would like to compare the degree of aggregation (or dispersion) of bacteria isolated from plant material. My data are discrete counts from leaf washes. While I do have xy coordinates for each plant, it is aggregation in the sense of the concentration of bacteria in high density patches that I am interested in. My attempt to analyze this was to fit negative binomial
