Which one of the following can be considered as appropriate pair of values of regression coefficient of y on x and regression coefficient of x on y ?

Options

  1. A(1,1)
  2. B(-1,1)
  3. C(- 1 2 , 2 )
  4. D( 1 3 , 10 3 )

Correct answer

A. (1,1)

Step-by-step solution

The product of regression coefficient of y on x and regression coefficient of x on y is always less than or equal to 1 . Also, the signs of both coefficients should be same. Here, | x |=1
