Please do give reproducible example. The code you gave, which you claimed `works correctly' doesn't: > SDT.Optim <- function(crit = NULL, Hess = F) + { + q <- length(par); x <- data + if(hasArg(crit)) + cat("\n Crit present\n") + else +

I wanted to use the nls() module to solve a Problem from Sen & Srivastava (1990, p.209). Here is the (basic) code used to perform the estimation: library(SenSrivastava) library(nls) data(E9.8) # Use Linear Least Square for estimating start values lm.obj <- lm(R.1 ~ I.1 + S.1, data = E9.8) nls1.obj <- nls(R.1 ~ b.0 + b.1*(I.1^a.1-1)/a.1 + b.2*(S.1^a.2-1)/a.2,

Dear ladies and gentlemen, I have recently installed the latest version of R (4.3.3) for windows. Now I have the following problems with mutated vowels like ?, ?, etc. Here is an example: If I type the command: Dir <- "C/Users/macho/Documents/_LVn/Experimentelle ?bungen" in the R console there is no problem. However, if I put the same command into a source file (e.g. Test.r) and call

Hi, I am running glm logit regressions with R and I would like to test a linear combination of coefficients (H0: beta1=beta2 against H1: beta1<>beta2). Is there a package for such a test or how can I perform it otherwise (perhaps with logLik() ???)? Additionally I was wondering if there was no routine to calculate pseudo R2s for logit regressions. Currently I am calculating the pseudo R2

Dear R Users, Here is another probelm/question. I would like to run some panel regressions with R. Therefore I have combined several time periods of data for different individuals in my database. I have already run pooled OLS but I would need to calculate a Fixed Effects Estimator (within estimator). Unfortunately I couldn't find anything like that in the RSearch and I suppose that lme

Dear list members, I have a question concerning multiple comparisons after using glm. My response variable is days until emergence of an insect species. The explanatory variables are sex (two levels), parasitoids added (two levels) and populations (34 levels). I would like to know now which populations are different in days until insect emergence. For this I used multiple comparisons as

Hi all, I thought that readers of R-Help might find the following article at ScienceNews of interest: Odds Are, It's Wrong Science fails to face the shortcomings of statistics By Tom Siegfried March 27th, 2010; Vol.177 #7 (p. 26) http://www.sciencenews.org/view/feature/id/57091/title/Odds_are,_its_wrong Regards, Marc Schwartz

Hi, David H.H. announced recently that jquery is going to be the default in Rails 3.1, and that Prototype helpers / RJS are going into a gem. What does that mean for the future? Should we progressively forget about things like javascript helpers, RJS, and all these fun parts of rails? And start coding with jquery/json in mind? I''m not against that at all, but I have to admit I find RJS

Hello, I had downloaded the samba 2.2.7a tarball, the pubkey and the samba-2.2.7a.tar.asc files from your website. The import of the samba-pubkey.asc works probably, but by the verify I get the errormessage that no path to this signature is defined and the signature can't verified. The distribution of Linux is the SuSE 8.0 and I used this lines. gpg --import samba-pubkey.asc

Dear Siegfried, I believe your boss is wrong saying that: >He also tried to explain me that the monthly means >(based on the daily measurements) must follow a >log-normal distribution too then over the course of a year. every statistician know that increasing the sample size the sample distribution of the mean is proxy to a gaussian distribution (Central Limit Theorem) independently

Hello, I'm currently dealing with a rather strange problem when using the function "stepAIC" ("MASS" package). The setting is the following: From model learning data sets ("learndata"), I want to be able to build prediction functions (in order to save them in a file for further use). This is done by the function "pred.function" (see below). Therein,

Hello, I am not sure if I am posting in the correct forum, but it seems somewhat zfs related, so I thought I''d share it. While the machine was idle, I started a scrub. Around the time the scrubbing was supposed to be finished, the machine panicked. This might be related to the ''metadata corruption'' that happened earlier to me. Here is the log, any ideas? Oct 24

I am trying to run the following model in R > lmer(leaves.eaten~Geocytotype+(1|TEST/ PLANT),data=cyphoplantfeeding,family=poisson) My experimental setup is 41 replicates (TEST) of an experiment in which there are three Geocytotypes of a plant species in each TEST, and two plant pseudoreplicates per Geocytotype in each test (i.e. 3*2=6 plants per test). So my random factors are trying

this works: onclick=''new Effect.Scale(this,50);'' but this does not: onclick=''new Effect.Scale(this,50,{queue:front}); new Effect.Scale (this,200,{queue:end});'' what is the correct syntax for using queue ? many thanks as I have just started wrapping my head around scriptaculous g

Hi * and thanks for you responses some body help me stop effect, just last effect. Thanks! to somebody help me with: Pulsator = Class.create(); Pulsator.prototype = {initialize: function(element) { this.stopped = false; new Effect.Pulsate(element, { afterFinish: this.action.bind(this) }); },action: function(element){if(!this.stopped) new Effect.Pulsate(element, { afterFinish:

hi again How can i extend 5 times for effect.pulsate beats? I need that continue beat until other event client happened about my other mail, is there other solution more elegant that this? : new Effect.Pulsate(leccion[i_leccion],{duration: 5,from: 1}); thanks again rag

Lets say I have an * at my business, with 7960 SIP phones. All the sip phones are registered using their extension number (like 305), but I would also like to put my SIP URI on my business card and in a name format, not an extension number (like lee.goodman), so that the SIP URI would read lee.goodman@asterisk.company.com. How would I set this up in extensions.conf? I got

var v1 = { a: ''value for a'', b:''value for b'' } var v2 = { c: ''value for c'', d: function(){some code...} }; var v3 = v2.merge(v1); I''m getting an error doing this... what is wrong?

Hey cats, I seem to have ran into a problem in IE trying to use parentNode with the cleanWhitespace method. doing something like: var div = $(''mydiv''); Element.cleanWhitespace(div); works really great, but try doing: var div = $(''mydiv''); Element.cleanWhitespace(div.parentNode); or var div = $(''mydiv''); div = div.parentNode;

Hello all, I wanted to announce a new R search engine I made that covers all the major R mailing lists, CRAN, r-project.org, and more. Results are tabbed, so you can refine the search. Current refinements include searching just the mailing lists, searching just introductions, and searching the web for source files ending in .R. Please send comments and suggestions.
