R help - Jun 2012 - Decision Trees or Markov Models for Cost Effectiveness

Hello,

I was just assigned to perform a cost effectiveness study in healthcare.  We are
studying the cost effectiveness of a proposed diagnostic vs. current screening
procedures.

One of the team members suggest a commercial software package called
"TreeAge Pro".  Looking at the description, it appears to be a nice
GUI to some very simple models that could be easily constructed in R.

Are there any packages in R for this type of analysis?  
Additionally, does anyone have any suggestions in general regarding doing this
type of analysis in R?

Thank You,

?We are studying the cost effectiveness of a proposed diagnostic vs. current

-- Please! -- Do you think this really describes your problem
sufficiently for a coherent answer? What sort of data do you have? --
what are the measures of cost and effectiveness? -- How complete are
your data? -- Is there censoring, missing values? What are the
covariates? How measured and recorded? ...

I would strongly recommend that you consult with fellow local
statisticians. At the very least, they might be able to point you in
the right (R package) direction. But I think you need a good deal more
help and guidance than that to formulate the questions, both
scientific and statistical.

hi Noah, you might want to look at http://goo.gl/KqXpJ -- haven't played
with it, and was actually surprised because whenever i think about decision
trees -- which as you know are completely different from CART type of
models -- i tend to think of excel add-ons or treeage. interested in
learning what you think about the package

Hi Noah,

I did ask basically the same question about a year ago and there
wasn't anything around
(http://tolstoy.newcastle.edu.au/R/e14/help/11/06/3651.html)
Although I agree that R would be very suitable for this kind of
calculations exist. I guess one reason is that a decision tree is not
really a branch of statistics. The  advanced user of a decision tree
will more likely program something in Excel.
If you find something, please let us know.

Best,
Stefan
