I am having difficulty understanding how regressions perform. I have
2 vectors (x = [4, 4, 0], y = [3, 6, 3]) and want to map y to x. When
this is done using a regression formula, I get a = 3 and b = .375.
Now, when I map x to y I get a = 0 and b = 2/3. Why is the second
result not the reflfective inverse of the first?(about the line y =
x)?
