RANK ANALYSIS OF MICROARRAYS (RAM)

We provide R codes used in Lee, Gray, Bjorkbacka, Freeman.(2005).

Threshold Regression (Test Version)

We provide SAS, R, and STATA software packages (all the packages are still in beta versions currently, you are welcome to test them and send us your feedbacks) to implement threshold regression as discussed in
