As I am reading ?arima, only NA entries in the argument fixed= imports. The following seems to indicate otherwise: x <- arima.sim(model=list(ar=0.8), n=100) + (1:100)/50 > t <- 1:100 > mod1 <- lm(x ~ t) > > init1 <- c(0, coef(mod1)[2]) > fixed1 <- c(as.numeric(NA), 0) > > arima(x, order=c(1,0,0), xreg=t, include.mean=FALSE, init=init1, fixed=fixed1) Call: arima(x = x, order = c(1, 0, 0), xreg = t, include.mean = FALSE, fixed = fixed1, init = init1) Coefficients: ar1 t 0.9281 0 s.e. 0.0357 0 sigma^2 e...

Hi all, I have major heterogeneity in variances across labs (100-fold). There is no apparent variance heterogeneity across y-hat. By using lme4 in the following way, am I accounting for the variance differences in labs?: lmer(y ~ fixed1 + covariates + (fixed1|labs)) I'm not sure that it is - I think it is only allowing the means (slopes [conditional means] & intercepts) to differ between labs. If so, how does one appropriately model such variances differences? Thank you in advance, JJ [[alternative HTML version delete...

It seems it was only locking up in the context of nouveau_hw_save_vga_fonts, when it actually did something (because the console wasn't already in graphics mode).

This patch series adds TV-out modesetting support to the KMS implementation. I've tried to test it on all the hardware I've got at hand (that is nv11, nv17, nv34, nv35, nv40, nv4b) with every possible output combination; I believe it has reached a mergeable state, however it depends on some commits from drm-next that haven't got into Linus' tree yet, if you agree to merge this

R users, How come R doesn't have a mascot? Linux has one and so does LaTeX, so shouldn't R? I personally think that associating a "friendly face" with R would be a good thing for R (one letter names can be quite intimidating). I apologize if this is addressed in the FAQ. I searched the FAQ as well as the mailing list archives and checked ?mascot but to no avail. ;-)
