Is there an existing function to compute Cook-Weisberg confidence curves for non-linear model parameters in R?

...to tell me is that the X-Fi drivers are junk. What I'm trying to understand is why every other sound program on the system works well with it, but Wine won't recognize it at all. Maybe a clue is that the X-Fi driver doesn't provide the legacy OSS interface?

I would like to write a function that computes Tukey's 1 df for nonadditivity. Here is a simplified version of the function I'd like to write: (m is an object created by lm): tukey.test <- function(m) { m1 <- update(m, ~.+I(predict(m)^2)) summary(m1)$coef } The t-test for the added variable is Tukey's test. This won't work: data(BOD) m1 <- lm(demand~Time,BOD)

Using SUSE Linux, Windows 32 bit and Windows 64 bit R 3.0.2 , I am unable to use R CMD check successfully.

Can anyone explain what I'm doing wrong here: > fred <- data.frame() > class(fred) [1] "data.frame" > test.fn <- function(x,class=class(x)) {class} > test.fn(fred) Error in test.fn(fred) : promise already under evaluation: recursive default argument reference or earlier problems?

I'm running Wine 0.9.2 on FC2, I was under the impression that this was the latest stable version, but I did some looking around and found that it's simply the latest version with official RPMs from the wine project. Is there a reason the RH/FC packages have not been updated in over half a year? Is there just a new place where I should be getting them from?

Dear all How should one parse all.equal() output? I'm specifically referring to the 'mean relative difference' messages. For example, > all.equal(pi, 355/113) [1] "Mean relative difference: 8.491368e-08" But I'm not sure how to understand these messages. When they're close to 0 (or 1xe-16), then it's intuitive. But when they're big, > all.equal(1, 4)

Hello, I am new to R, and I am trying to figure out how to use it for a random effects model. I am using version 2.4.0, and I also have the book Applied Linear Regression by Sanford Weisberg. I have four variables: Swimmer, Sex, Swim, and Difference. Swimmer identifies the number assigned to a particular person. Sex is male/female. Swim identifies the number swim from 1 to 6. Difference

How I can do to appear all Windows Programs Shortcuts automatically in my "Applications" menu on Ubuntu? Thank you! Ale (hope I not be dreaming or expected too much of wine so sooner :)

How does one go about getting a newer version of an application added to the AppDB in order to provide reports as to what does and does not work with that version of the application when run via Wine? In particular I'd like to add my observations regarding v4.31 of Pegasus Mail but it is not one of the listed versions. -- Jim

Well I have installed Ubuntu 8.40, Wine 9.59, and World of Warcraft, and it took me some time to get it working, but I finally did. Now, however, I'm having several problems with the way it runs. Namely: -the mouse is very slow and skippy at moving when in WoW -lots of objects in the game fail to render (the ground usually doesn't render either) -my FPS in the middle of nowhere, with

I have a question regarding customising contrasts for linear models I read the section in Fox/Weisberg's CAR (2nd ed.) and was thinking--apparently erroneously--that the following two snippets would do the same: # approach 1: default treatment contrasts # generate data set.seed(1111) y <- c(rnorm(1000, -1), rnorm(1000, 0), rnorm(1000, 1)) x <- factor(rep(letters[1:3], each=1000)) #

I have a doubt about the calculation of tests for fixed effects in mixed-effects models. I have read that, except in well-balanced designs, the F statistic that is usually calculated for ANOVA tables may be far from being distributed as an exact F distribution, and that's the reason why the anova method on "mer" objects (calculated by lmer) do not calculate the denominator df nor a

Hi,   I have a system in which I analyze 2 subjects and 1 variable, so I have 2 models as follow:   y ~ x_1[, 1] + x_2[, 1] + x_1[, 2] + x_2[, 2]   Where   x_1[, i] = cos(2 * pi * t / T_i) x_2[, i] = sin(2 * pi * t / T_i)   i = 1, 2   Data have two columns: t and y.   As you can see, I have a multiple components model, with rithm and without trends, and I have a fundamental

Hello, All: The vignette with the sos package used "upquote.sty", required for R Journal when it was published in 2009. Current CRAN policy disallows "upquote.sty", and I've so far not found a way to pass "R CMD check" with sos without upquote.sty. I changed sos.Rnw per an email exchange with Prof. Ripley without solving the problem; see below. The

I have been taking a break for the last month or so, and am only just now catching up on my email. Otherwise, I would have joined this discussion earlier. And... I apologize for the length of this, but I don't think it is overly long. >From the amount of activity in the LispStat news group (none), it seems that LispStat is dead. We all know that Luke is working on R and not on LispStat,
