...lyse the regression but I'm getting the folowing error message > lm98<-lm(log(U+1)~Bq+Gi+Lv+Tb+Bq:Gi+Bq:Lv+Bq:Tb+Gi:Lv+Gi:Tb+Lv:Bq) > plot(lm98) Error in plot.window(xlim, ylim, log, asp, ...) : need finite ylim values In addition: Warning message: NaNs produced in: sqrt(1 - hii) The response variable is tranformed by a log function but I'm adding 1 so that the 0 don't become inf.

Hii, I will save the elements of the vector median<-with(x, tapply(V3, grup, median)). The output of this vector is: 25 50 75 100 125 150 175 200 225 250 275 300 325 350 375 400 425 450 475 500 17.8 17.8 17.5 17.8 17.7 17.6 17.7 17.6 17.8 17.7 17.6 17.7 17.8 17.7 17.8 17.8...

I have a puzzle as to how R is computing Cook's distance in weighted linear regression. In this case cook's distance should be given not as in OLS case by h_ii*r_i^2/(1-hii)^2 divided by k*s^2 (1) (where r is plain unadjusted residual, k is number of parameters in model, etc. ) but rather by w_ii*h_ii*r_i^2/(1-hii)^2 divided by k*s^2, (2) i.e. has the weight in there. Apart from the division this is su...

Hii, Is it possible, to use the plot() funktion and the boxplot() funktion together ? I will plot a simple graph and additionally to the graph on certain places boxplots. I have imagined to plot the graph a little bit transparency and show in the same graph on certain places boxplots.... Is it possib...

It seems that the standardized deviance residulas, that one gets on plots of a glm.object x with plot(x) are calculated as r <- residuals(x) s <- sqrt(deviance(x)/df.residual(x)) w <- weights(x) hii <- lm.influence(x)$hat r.w <- if (is.null(w)) r else (sqrt(w) * r) rs <- r.w/(s * sqrt(1 - hii)) This implies that, for example, for binomial B(ni,pi) data the devaince residials (which are just r) are weighted not only with sqrt(1-hii), but also with 1/sqrt(ni) and s, leading to absurd...

Hii.. Could anyone please tell me how to draw 3D histogram in R I have a 20X3 matirx. Now I want 2 of the variable on X and Y axis .And Height of the bar should denote the value of third variable. Thanx Sumit [[alternative HTML version deleted]]

Hii, I created some boxplots with this commands: x <-read.table(file="test.txt") x$group <- rep(1:8, each=5) boxplot(V3~gruppe, data=x) Now, I will connect the boxplots to each other to the min, max and median values. Can anybody help me how to do it ? greetings, J -- View this...
