Question

Analyze regression of X on Y if X = -3.4 + 1.04Y

Answer 1

The regression equation of Y on X is Y= 0.929X + 7.284 Example 9.10 Calculate the two regression equations of X on Y and Y on X from the data given below, taking deviations from a actual means of X and Y.

Answer 2

The analysis is given below:

• The line of regression shows the regression.
• The line of regression is shown by Y=aX+b.
• Here, X and Y are variable values and a and b are constants.
• In the given question, the line of regression is X=-3.5+1.04Y.
• It is a linear case of regression.
• Y can be found by, Y=(X+3.4)/1.04.
• The average value of X is -3.4 when Y is 0 and That of Y when X is zero is 3.27.
