Question
Bring out the inconsistency in the following:
bYX = 2.6 and bXY = `1/2.6`
Advertisements
Solution
Given, bYX = 2.6 and bXY = `1/2.6`
Here, bYX and bXY have the same signs.
Also, bYX > 1 and bXY < 1
Also, for consistent data, the signs of bYX and bXY are same and bYX > 1, bXY < 1
Here, bYX. bXY = 1
∴ The given data is consistent.
