...work properly and by plugging in my data I can also get the lines plotted on my dataset. Unfortunately I'm running into a problem with the median and other regression lines with tree age younger than 50 years, basically the median is in this range overestimated and even comes out of the rage of oberservations. here is the code I'm using. # then fit the median using nlrq spruce.nlrq <- nlrq(height ~ SSlogis(age, Asym, mid, scal),data=spruce, tau=0.5, trace=TRUE) lines(1:200, predict(spruce.nlrq, newdata=list(age=1:200)), col="2") I believe  this has something to do with the SS...

Dear friends, I have used R for some time now and have a tricky question about the coxph-function: To sum it up, I am not sure whether I can use coxph in conjunction with missing covariate data in a model with time-variant covariates. The point is: I know how "old" every piece that I oberserve is, but do not have fully historical information about the corresponding covariates. Maybe you have some advice for me, although this problem might only be 70% R and 30% statistically-related. Here's a detailled explanation: SITUATION & OBJECTIVE: I want to analyze the effect of environme...

...-4.466e-09 6.814e-02 5.294e-09 Degrees of Freedom: 4035 Total (i.e. Null); 4032 Residual Null Deviance: 3.371e+16 Residual Deviance: 3.355e+16 AIC: 131500 Is this right? And how can the output be interpreted? Did I even answer the question, and how can I plot a curve to the oberservations? /Thank you so much for helping -- View this message in context: http://www.nabble.com/Generalized-linear-models-tp23265349p23265349.html Sent from the R help mailing list archive at Nabble.com.

Hello everybody, i oberserve a strange behavior of libvirtd. I have an xen vm (HVM, windows xp) that i restore from an statefile. If i do so, it works. But if i do that in an loop, where i restore the vm, let it run 60 seconds, destroy it, wait 30 second, and then i restore again, it runs 91 times and then libvirt crashed and...
