RE: st: cumulative probabilities under competing risks with covariate adjustment

["Allen Buxton" <ABUXTON@childrensoncologygroup.org>]

-Thank you.  This is a timely post as I was just working with cmprsk this week. I have one comment. On investigation, I find that in Windows XP rsource needs an 'r' added to the end of the rpath() option and the R option, --save, in order to run and print the R-results in the Stata log. (Also the R function savePlot() had to be taken out of the .R file).

rsource using `"C:\...\note02.R"',rpath(C:\Program Files\R\R-2.6.2\bin\r) roptions(--save)

this is the same as the Stata shell

shell C:\Program Files\R\R-2.6.2\bin\r --save  <"C:\...\note02.R"> "C:\MyPrjct\Rexm00\junk.Rout"

Thanks,
Allen

Dear Uri Goldgerg,

thanks for using -stcompet-

At the last Italian Stata Meeting prof. Bill Gould said that the competing risks matter is in the "wish" (or "doing") list of the Stata Corporation.
Since this is a public mail I believe that prof Gutierrez or Gould could directly give a more precise reply.

The -rsource- command, written by R. Newson, allows to run R from within Stata. So, in the meanwhile you could use the -cmprsk- R-package from within Stata and import the results.

As further Stata opportunities in competing risks, even if not directly addressing our problem, there is -stpepemori- available on the SSC archive, testing the equality of two cumulative incidence functions, and new codes of
-strs- (a command estimating relative survival) that allows to compute cumulative incidence without knowing the cause of death, making use of the expected probabilities of death. This new version of -strs- is not yet available on the web but I can send on request the preliminary version.

Best wishes.

Enzo
