Question

What is the regression equation for predicting Y from X? And, Calculate the predicted Y for each X value, and find SS_residual.

No Excel, No handwrites, and please provide formulas or steps.

                 X      Y

               5     10

               3       6

               6       7

               4       3

               2       4

Answer 1

from above : Line equation: Y^ =2+1*x

from above line equation:

		predicted value
x	y	y^=(2+1*x)	residual(y-y^)	residual^2
5	10	7	3	9
3	6	5	1	1
6	7	8	-1	1
4	3	6	-3	9
2	4	4	0	0
			total	20

from above:

SSresidual =20
