Sum
Bring out the inconsistency in the following:
bYX + bXY = 1.30 and r = 0.75
Advertisement
Solution
Given, bYX + bXY = 1.30, r = 0.75
Consider, `("b"_"YX" + "b"_"XY")/2 = 1.30/2 = 0.65`
∴ `("b"_"YX" + "b"_"XY")/2 < "r"`
But, for consistent data `|("b"_"YX" + "b"_"XY")/2|` >|r|
∴ Given data is inconsistent.
