WebMar 21, 2024 · The interpretation of standardized regression coefficients is non-intuitive compared to their unstandardized versions: For example, a 1 standard deviation unit increase in X will result in β standard deviation units increase in y. A change of 1 standard deviation in X is associated with a change of β standard deviations of Y. WebGiven: Two regression lines are 6x + y = 30 and 3x + 2y = 25. As we know that, the two lines of regression intersect each other at ( x ¯, y ¯) By solving these two equations: 6x + y = 30 and 3x + 2y = 25. We get ( x ¯, y ¯) = ( 35 9, 20 3) We can write 6x + y = 30 as line of regression of x on y: x − 35 9 = − 1 6 × ( y − 20 3 ...
