Hi All, I am in the middle of doing an analysis of a Case-Cohort design. I had three questions about the analysis:
a) Does any one know of some public code for developing the patient risk sets (indexed by failure time) or is there a better way to organize the data? b) I was planning to use the Barlow weighting method. Has this or any other weighting method (Prentice, Self-Prentice) been implemented in R? c) Is matching a good thing to do or can the variables that would be used for matching just be adjusted for in the cox regression (is there a reference for this because I can’t find one)? If matching is a good thing to do are there any R packages that contain matching functions? Thanks for your help.
