I have a simple set of 10 data points
My ten Data Points
2
3
3
4
5
8
9
11
11
13
(mean = 6.9)
My prediction nodel predicts the following values for the ten data points (listed in same order)
2
3
4
5
6
7
9
10
11
12
I calculate
SST = SIGMA (VALUE  MEAN)^2 = 142.9
SSM = SIGMA (MODEL  MEAN)^2 = 108.9
SSE = SIGMA (VALUE  MODEL)^2 = 6
I thought SSM + SSE = SST, but
SSM + SSE = 114.9 which doesn't equal 142.9
Where am I going wrong?
