Normal tests disagree?
If I have data that I feed into shapio.test and jarque.bera.test yet they seem to disagree. What do I use for a decision? For my data set I have p.value of 0.05496421 returned from the shapiro.test and 0.882027 returned from the jarque.bera.test. I have included the data set below. Thank you. Kevin "Category...

[RHSA-2004:360-01] Updated kernel packages fix security vulnerabilities (fwd)
OK, this is the first important vuln I've seen since joining the centos list, and represents a good opportunity to ask "What happens now?" Do you accept contributed rebuilds? What is the rebuild/test/release procedure? Is there anyone who is tracking time between RH releases and centos yum repo updates? What can I do to help? thanks, -ryan -- Ryan Sweet <ryan.sweet at aoes.com> Advanced...

Yes, it's a ".0". We've been through this. At this point, I could care less what you think of the 2-2-2, 6-6-6 model. I _never_ said it's the "best." I just said that many of us believ...

help with pasting + expressions?
I can't believe I'm having such a hard time with this and I haven't been able to find out how to solve this... lab <- expression( paste( hat(v), as.character(round(y.hat,2)), ",", hat(sigma)^2, as.character(sigma.hat)) ) text( x=pt$x+2, y=pt$y,labels=lab ) ## the text should be \hat{y} = <value of y.hat>, \hat{\sigma}^2 == <value of sigma.hat> and R keeps displaying the actual text of the non-expressions....

Hat values for generalized additive models
...ight for the following question, please? Setting: estimation of prediction intervals for age-period-cohort models using GAMs (rate ~ s(age,period)) Method: bootstrap (Davison and Hinkley, 1997) Issue: standardisation of the residuals for resampling requires an adjustment using the diagonals of the hat matrix. Is there a simple way to get the hat values out of a GAM object? Looking through the code, I couldn't see anywhere where the hat matrix is constructed. I tried the appended patch (against mgcv_0.8-1.tar.gz). This returns sensible hat values for normal errors, however the hat values u...

It's good enough that HP is losing lots of clients because HP (among other tier-1 OEMs short of IBM) is finding that Linux their support is sub-par. Even Dell and others are just farming suppor...

Variance-covariance matrix for beta hat and b hat from lme
Dear all, Given a LME model (following the notation of Pinheiro and Bates 2000) y_i = X_i*beta + Z_i*b_i + e_i, is it possible to extract the variance-covariance matrix for the estimated beta_i hat and b_i hat from the lme fitted object? The reason for needing this is because I want to have interval prediction on the predicted values (at level = 0:1). The "predict.lme" seems to provide point estimates only. The predicted value for new observation of the i_th subject, with E_i and F...

Help with functions as arguments
...tion(x, z) {     y = x*z -2     y } Where I am running into trouble is when I want to call function f1 within function f2: f2(x = 3, z = f1(x)) This returns the error: "Error in f1(x) : object 'x' not found" I'm not sure how to define environments within the functions so that the just-defined 'x' may be passed as an argument to f1 within f2. Any help would be greatly appreciated! Ian Renner [[alternative HTML version deleted]]

R2 always increases as variables are added?
Hi, everybody, 3 questions about R-square: ---------(1)----------- Does R2 always increase as variables are added? ---------(2)----------- Does R2 always greater than 1? ---------(3)----------- How is R2 in summary(lm(y~x-1))$r.squared calculated? It is different from (r.square=sum((y.hat-mean (y))^2)/sum((y-mean(y))^2)) I will illustrate these problems by the following codes: ---------(1)----------- R2 doesn't always increase as variables are added > x=matrix(rnorm(20),ncol=2) > y=rnorm(10) > > lm=lm(y~1) > y.hat=rep(1*lm$coefficients,length(y)) > (r.squar...

How does predict() calculate prediction intervals?
For a given linear regression, I wish to find the 2-tailed t-dist probability that Y-hat <= newly observed values. I generate prediction intervals in predict() for plotting, but when I calculate my t-dist probabilities, they don't agree. I have researched the issues with variance of individual predictions and been advised to use the variance formula below (in the code). I...

LD50 and SE in GLMM (lmer)
...I used the following to get predicted values (thanks to a post by John Maindonald (I'll attach his post below)): model4 <- lmer (y~time + (1|blc/instar),family=binomial(link="probit")) summary(model4) b <- fixef(model4) X <- (model.matrix(terms(model4),zerotest)) hat <- X%*%b pxal <- pnorm(hat) # probit link, for logit it would be: pval <- exp(hat)/(1+exp(hat)) pval Once I get the pval, I see where the 0.5 predicted value lies and I adjust the x's in zerotest to be more detailed in that range, eg. x: 1-420hours, I see that 0.5 is in the 32...

R plot : hat symbol and cex.lab
Hello, Does anybody know how to make the "hat" correctly appears in the label of this plot (with this cex.lab coefficient) : plot(1:10, 1:10,ylab = expression(hat(h)),cex.lab = 1.5) The "hat" does not completely appear on my graph, it is like cut on the left side. It tried to change the margin : par(oma=c(0,2,0,0)) plot(1:10,...
