millisys Posted September 19, 2014 Author Posted September 19, 2014 Hi jchd, I use a simple linear regression where R2 = 1. The weighting is associated with the records, and your question is a good one; when combining devices, the shared device is only considered once.
jchd Posted September 19, 2014 Posted September 19, 2014 Sorry to being thick today but I don't get what your R2 means. Say an hypothetical combination contains the following devices: #001(2.42) #002(0.96) #004(0.00) #007(-6.67) #015(-4.20) #005(2.37) How precisely do you compute the resulting gain?
