Answer one of the two questions below (not both):

  1. Name and describe a business question that you could answer using a decision tree. What data would you collect to perform the analysis? Don’t use an example we’ve covered in class.
  2. What advice would you give someone regarding how to select the right predictor variables for a decision tree analysis?

Here is the question:

Do a little bit of research and come up with an example of how R is used. You can describe either a company using R and what they use it for, a news story about how companies are using it, or an interesting package that does some interesting functionality. Write one to three sentences on what you found and the URL where you found it.

(Hint: Just Google “companies using R” or “applications of R” or something like that. Examples aren’t too difficult to find)
