Implementing a decision tree in R

Показать описание
I had a question on Twitter about implementing a decision tree in R. Here is a short video giving at least one approach to implementing a decision tree. We code the model so that it can work with a single set of parameters or multiple sets of parameters so our sensitivity analyses are easy to run.

Hi Tristan! Wonderful work, thanks! Can you please include in your future videos a guided video on how to write a macro in VBA (excel) for one-way or two-way deterministic sensitivity analysis? Thanks for sharing your knowledge!

Thank you! I have found this a really good starting point for a budget impact analysis model. If you have any guidance about choices for distributions (even references to read) that would be really appreciated!

This is a great video, but what shortcut did you use to increase the size of the vertical bar to write over 3 lines at 10.53? Looks super useful!

It's really helpful, thank you! Could you please explain why you set shape = 100 and 25? Are there any criteria for using these values? Sorry I could not catch up with this.
