cov.unscaled in gls object
Hi list, can I extract the cov.unscaled ("the unscaled covariance matrix") from a gls fit (package nlme), like with summary.lm? Background: In a fixed effect meta analysis regression the standard errors of the coefficients can be computed as sqrt(diag(cov.unscaled)) where cov.unscaled is (X'WX). I try do do this with a gls-fit. Thanks, Sven

cov.unscaled in NLS - how to define cov.scaled to make comparable to SAS proc NLIN output - and theoretically WHY are they different
I am running a 3-parameter nonlinear fit using the default Gauss-Newton method of nls. initialValues.L = list(b=4,d=0.04,t=180); fit.nls.L = nls( myModel.nlm , fData.L, start = initialValues.L, control = nls.control(warnOnly = TRUE), trace=T ); summary.nls.L = summary(fit.nls.L); I run the same analysis in SAS proc NLIN. proc nlin data=apples outest=a; parms b=4 d=.04 t=180; model Y =

No convergence using ADAPT
I am trying calculate a probability using numerical integration. The first program I ran spit out an answer in a very short time. The program is below: ## START PROGRAM trial <- function(input) { pmvnorm(lower = c(0,0), upper = c(2, 2), mean = input, sigma = matrix(c(.1, 0, 0, .1), nrow = 2, ncol = 2, byrow = FALSE)) } require(mvtnorm) require(adapt) bottomB <- -5*sqrt(.1) topB <-

lm() variance covariance matrix of coefficients.
Hi, I am running a simple linear model with (say) 5 independent variables. Is there a simple way of getting the variance-covariance matrix of the coeffcient estimates? None of the values of the lm() seem to provide this. Thanks in advance, Ritwik Sinha rsinha@darwin.cwru.edu Grad Student Case Western Reserve University [[alternative HTML version deleted]]

Scaled or unscaled variance covariance matrix
Hi, does anyone know which of the scaled or unscaled version of the variance-covariance matrix of regression coefficients (as produced by ls.diag) is the correct one, or when one is better than the other? I am interested in univariate linear regression (lm). Thank you very much. Dipl.-Psych. Johannes Ullrich Philipps-Universit?t Marburg Fachbereich

"font problems in X11 with linux R"
Hello, I''m inexperienced with linux, X11 and R. A font problem have surfaced.

X11 fonts and Ubuntu
Hi, I am moving from Windows XP to Ubuntu 6.10 and installed R 2.4.0. When I run eg plot.lm (things work fine with plot.default - eg plot(rnorm(30),rnorm(30))) plot(lmobject) I can get the first plot and then this message: Hit <Return> to see next plot: Error in text.default(x, y, labels.id[ind],cex=cex, xpd=TRUE, : could not find any X11 fonts Check that the Font Path is correct

Font problem
Some plots fail due to a problem with the X11 fonts. I get a message that "X11 font at size 22 could not be loaded." The demo() graphics routine for instance dies during the third chart. The graphics demo calls "font.main=1" and that seems to be where the error is. I believe this is due to a configuration problem on my system, however I can't find where in the

X11 Fonts sizes
In postscript graphs (pointsize = 10, different sizes in graph adjusted via cex) I would like to use different font sizes but get the following warning message: Warning messages: 1: X11 used font size 8 when 9 was requested 2: X11 used font size 8 when 7 was requested 3: X11 used font size 8 when 5 was requested This is probably not a R but a X11 problem, nevertheless I would be most

aov design questions
R developers, I have a first attempt to make an aov function. Eventually I want to build in Error() structure, but first I am trying to get this presentable for balanced data with only a single stratum, just using residual error. I am following R. M. Heiberger's Computation for the Analysis of Designed Experiments, Wiley (1989) I a using a wrapper (aov.bal) to call the

How to use a saved SVM model from e1071
Hello, I have an SVM model previously calibrated using libsvm R implementation from the e1071 package. I would like to use this SVM to predict values, from a Java program. I first tried to use jlibsvm and the "standard" java implementation of libsvm, without success. Thus, I am now considering writing data in files from my Java code, calling an R program to predict values, then gather

X11 font troubles (Knoppix/Debian unstable)
I'm getting Error in strwidth(...) : X11 font at size 15 could not be loaded kinds of errors when I try to change cex to something *other* than 1 (works OK otherwise). I can't get through to RSiteSearch() right now, but as I recall my search of it only revealed people who had problems because they had failed to install fonts: my Knoppix/tracking Debian unstable distribution claims
