RE: [HP12C] Angular coefficent from linear regression off by 1
I don't know either the 12C or the 15C very well but I have emulators on my phone ;)
So, correct me if I'm wrong, but the 12C doesn't have linear regression as a function, just xintercept and yintercept. So you calculate the slope in two steps: y  x=1 minus y  x=0 or 1 g(y,r) (11.25867251) 0 g(y,r) (0.15934086.19) X<>Y RDN  If you do the same on a 15C, you get the same result. But a 15C has a f(L.R.) function delivering the result without 10digit intermediate calculations. Hence the difference. Cheers, Werner 41CVâ€ ,42S,48GX,49G,DM42,DM41X,17BII,15CE,DM15L,12C,16CE
