Hi R-community, I've been trying to fit a model using maximum likelihood in nlm. Upon convergence I examine the hessian and it has a few (not all) positive values on its diagonal, as does its inverse. I am...

Dear R community, I'm curious to know how people go about estimating standard errors for parameter estimates after model selection by ridge regression and the lasso. Do you have any practical or theoretical advice? Warmly, Andrew -- Andrew Robinson Department...

Dear community, I'm trying to track down a quote, but can't recall the source or the exact structure - not very helpful, I know - something along the lines that: 80% of [applied] statistics is linear regression ... ? Does this ring...

Martin, check the Console application for error messages. They will help you/us diagnose the problem. During my installation I observed similar behavior, only to discover that I had yet to install the libreadline package from the download. Andrew -- Andrew...

Dear R-helpers, when in the browser, is it possible to change the environment, so as to be able to easily access (print, manipulate) objects in the parent, or elsehwere? I know that it is possible to evaluate expressions in...

Dear R community, I'm fitting a complex mixed-effects model that requires numerous iterations and function evaluations. I note that nlminb accepts a list of control parameters, including eval.max. Is there a way to change the default eval...

Hello all, Here's my query: Running R 1.6.2 on FreeBSD 5.0, and on WinXP, and I find that the following hangs the process: dchisq(alpha=0.01, df=1, ncp=295) but it does work for...

Greetings all, I'm trying to figure out how to calculate the inverse CDF (i.e. a quantile) for a non-central F distribution. I could put together a quick numerical solver routine using the CDF, but I wonder if...

Certainly. postscript("test.ps") par(new=T) plot(1:10,1:10) dev.off() Produces a postscript image that can be opened. However pdf("test.pdf") par(new=T) plot(1:10,1:10) dev.off() produces a pdf that...

Greetings R-friends, I'm looking for some code to fit an ARMA, up to (3,3), preferably with ML. I'm doing a simulation experiment, so I need to fit it to the order of millions of times. I...
