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? Tha...

Hello, I'm tasked with putting together a cost effectiveness analysis on a proposed medical treatment. The "standard" suggested by someone is an expensive commercial package names "TreeAge Pro" which looks like its just a fancy GUI on top of a decision tree. However, we don't have it and it is expensive to buy. Questions for the group: 1) Are there any interesting R packages for decision trees? 2) Has anyone here done a cost effectiveness analysis using R that I can s...

...ig R fan and user and in my new job I do some decision modeling (mostly health economics). For that decision trees are often used (I guess the most classic example is the investment decision A, B, and C with different probabilities, what is the expected payoff). We use a specialized software called TreeAge that some might know. The basic setup of such simulations is actually very simple and I guess useful in many fields. So I was wondering whether there is already a package out there in R that is doing such a thing? Thanks for any hints! Best, Stefan PS (By decision tree I don't mean cluster-l...
