Does anyone know how to make a plot like Fig. 4 of Paik, et al., New England Journal of Medicine, Dec. 30, 2004? Given survival data and a covariate, they plot a curve giving "Rate of Distant Recurrence at 10 Yr (% of patients)" on the y-axis versus the covariate on the x-axis. They also plot curves giving a 95% confidence interval. Thanks very much. -Ben The information in this

Hello all I would like to visualize the hazard ratios of a cox proportional hazards model. I have seen some good examples in the New England Journal of Medicine: http://content.nejm.org/cgi/content/short/353/26/2747/F3 http://content.nejm.org/cgi/content/short/350/26/2654/F2 (I hope these are open access, but I am not sure) And something similar in the book 'R Graphics' by Paul Murrell: http://www.stat.auckland.ac.nz/~paul/RGraphics/chapter1.html (Fig. 1.8) But th...

...in the r language and I discover that it the language that I need for my research. I don't too much yet about this language. I want to know if I can find in this language and install the package data set related to " The Framingham Heart Study", see references here: http://content.nejm.org/cgi/content/full/357/4/370 http://www.framinghamheartstudy.org/participants/original.html http://www.framinghamheartstudy.org/participants/offspring.html http://www.framinghamheartstudy.org/participants/genthree.html cheers Kalulu

...ith the groups as fixed effect using lme. I thought about using the jackknife procedure, i. e., removing any one subject and calculating the fixed effect, to assess the stability of the fixed effect and thereby validate the model. I suppose this has been done in the following study: http://content.nejm.org/cgi/content/full/357/19/1903 (this may be restricted access, sorry) Is such an approach feasible? Also in the article results are confirmed by comparing the mixed model with a fitted least-squares regression. I understand that this can be achieved with lmlist, but only for for models without...

This introduces support to run P2V without X server. Runtime parameters are specified via kernel command line making it hopefully suitable for automated migration with a little help of PXE boot. Patchset is not squashed and represents dev. history.
