Which of the following is false for pair of n values of X and y
A)bxy>1,byx<0 B)bxy>1,0<by<1
C)bxy>1,byx>1
D)bxy>0,byx<0
Answers
Answer:
1. byx = slope of the regression line of y on x which measures the change in variable y for a
unit change in variable x.
2. bxy= slope of the regression line of x on y which measures the change in variable x for a
unit change in variable y.
3. Correlation coefficient is symmetric i.e., ryx= rxy but regression coefficients are not
symmetric byx bxy .
4. When r = 0, both the regression coefficients are 0.
Step-by-step explanation:
Answer:
1. byx = slope of the regression line of y on x which measures the change in variable y for a
unit change in variable x.
2. bxy= slope of the regression line of x on y which measures the change in variable x for a
unit change in variable y.
3. Correlation coefficient is symmetric i.e., ryx= rxy but regression coefficients are not
symmetric byx bxy .
