Is there a statistical whizz here who is also a golfer?
I am having a little difficulty with one element of a calculation outlined
in the USGA's Handicap manual - ref here -
http://www.usga.org/playing/handicap...ection_17.html
My problem is I don't understand the underlying stats in Section 17.2b
Regression method, and I am not sure if I am interpreting the order of
claculations correctly in the formula - 5) Compute the difference factor (DF)

DF = (N x S4) - (S1 x S2) divided by (N x S3) - (S12)

Any assistance would be greatly appreciated
