similar to: Error using "White-corrected" Anova (white.adjust="hc3")

Hi all, It seems that I can get White's (HC3) test using MASS. The syntax I used for the particular problem is anova(scireg3, white.adjust="hc3") where scireg3 is an object from the lm function. But, the anova summary table is all I get. I don't get the new estimates or standard errors correcting for heteroskedasticity. Is there a way to get that information? Thanks

Is there a package that will allow me to fit Brownian motion and Ornstein?Uhlenbeck models of evolution for discrete traits? I know that geiger and ouch have commands for fitting these models for continuous traits, but these aren't suitable for discrete trait evolution, correct? -- View this message in context:

Dear friends i am trying to fit an Ornstein-Uhlenbeck process by MAXIMUM LIKELYHOOD method. i found these formulas on http://www.sitmo.com/article/calibrating-the-ornstein-uhlenbeck-model/ this is the mean-reverting process http://r.789695.n4.nabble.com/file/n4637271/process.txt process.txt and this is the script that i am using....... ouFit.ML=function(spread) { n=length(spread)

hello everyone, i'm trying to simulate a 2-parameter integrated ornstein-uhlenbeck (IOU) process, but i'm not sure exactly where to start (which package, which function). the motivation is the paper by taylor et. al. (JASA 1994) "a stochastic model for the analysis of longitudinal aids data." the model they suggest consists of a combination of fixed and random effects, a

Hi all, I'm running White's test to correct for non-constant error variance and I am using the Anova function in the package CAR. My command structure is > Anova(scireg3, white.adjust="hc3") where scireg3 is an object from lm. I get the message "Error in SS[i] <- SS.term(names[i]) : nothing to replace with" What does this mean and how do I fix it. Thanks

Hello, I am a new user of R and found the function dtnorm() in the package msm. My problem now is, that it is not possible for me to get the mean and sd out of a sample when I want a left-truncated normal distribution starting at "0". fitdistr(x,dtnorm, start=list(mean=0, sd=1)) returns the error message "Fehler in "[<-"(`*tmp*`, x >= lower & x <= upper,

Hello, I want to solve a nonlinear 3SLS problem with "nlsystemfit()". The equations are of the form y_it = f_i(x,t,theta) The functions f_i(.) have to be formulated as R-functions. When invoking "nlsystemfit()" I get the error Error in deriv.formula(eqns[[i]], names(parmnames)) : Function 'f1' is not in the derivatives table

As it turns out, on cards that actually have CRTCs on them we're already calling drm_kms_helper_poll_enable(drm_dev) from nouveau_display_resume() before we call it in nouveau_pmops_runtime_resume(). This leads us to accidentally trying to enable polling twice, which results in a potential deadlock between the RPM locks and drm_dev->mode_config.mutex if we end up trying to enable polling

Hello, Is there a possibility of setting parameter constraints in nls.lm() ? The documentation does not say anything on that explicitly. In order to achieve the same effect, the criterion function could be penalized outside the valid domain. Is that a correct procedure? Kind regards, Kilian [[alternative HTML version deleted]]

Is there a way to use R as a client server application? Whitch means: 1. install R on a server (running as a service) 2. from client send R-scripts through IDE/Editor (TINN-R) to "R-server" 3. receive R-output on client All the Best Kilian Schwab

Hi Has anybody done THD or THD-N measurements with the CELT Codec (bext would be on various bit rates) If someone could share results for Mono at 64kBit and Stereo at 128 and 196kBit it would be great. thank you very much Jochen -------------- next part -------------- An HTML attachment was scrubbed...

Hi there, I'm new to R but I thought this is the most likely place I could get advice or hints w.r.t the following problem: I have a series of measurements xi with associated uncertainties dxi. I would like to construct the probability density histogram of this data where each density estimate has an associated error that is derived from the dxi. In other words, for large dxi the

dear useRs, i'm working with a mean reverting model of the following specification: y = mu + beta(x - mu) + errorterm, where mu is a constant currently I estimate just y = x (with lm()) to get beta and then calculate mu = estimated intercept / (1-beta). but I'd like to estimate mu and beta together in one regression-step and also get the test-statistics (including parameter

Hi all, it is possible to invoke certain graphical functions (e.g. curve) with an expression argument, e.g. "ylab=expression(phi)". There are some greek letters with a second script. For instance, in latex two symbols do exist: phi and varphi. Is the second symbol also available in an expression()? If yes, how? Kind regards, Kilian

Hello, i have a linux box running samba as a fileserver for 4 Windows NT 4.0 Workstations. the performance is good on responing-times but loading and writing large files (more than 500 kByte) is too slow.

Hi rsync developers, I'm trying to get some fancy mirroring done with selecting files from a larger archive through the --files-from option. The only problem that I do see is that rsync will not eat the --delete option whatever I try. Thus, all the old files remain in the mirror archive instead of being deleted. To be more clearly, I want the rsync --files-from option to behave like

Dear all, I wanted to let you know about four phylogenetic comparative methods (PCM) packages that have become available on (3 on CRAN and 1 on GitHub) recently that hopefully will be interesting to somebody. Three of them go significantly beyond the Brownian motion (BM) and Ornstein-Uhlenbeck (OU) processes. 1) There is a new version of mvSLOUCH available. The most important change is that the
