Problems in linear regression
WebbThe two regression lines are 3X+2Y=26 and 6X+3Y=31. Find the correlation coefficient. Solution: Let the regression equation of Y on X be 3X+2Y = 26 Example 9.18 In a laboratory experiment on correlation research study the equation of the two regression lines were found to be 2X–Y+1=0 and 3X–2Y+7=0 . Find the means of X and Y.
