A = (FTF)-¹ FTY.
2. Having computed A from #1 above:
Y =
0 compute
I. Write down the equation of the best fit line
(i.e. the estimation function), noting that the
first entry of A is the intercept and the
second, the slope.
II. Compute Ŷ = FA, i.e. where the data point
should have been to lie exactly on the line.
3. Next, compute the least squared error
2
E = ||Y – Y||
NOTE: All computations must be done by hand.
