Question

Derive a formula for βˆ

1 given that β0 = 0 (i.e. the underlying linear model is Y = β1x + . In

others words, we are looking for least squares fit for where Yˆ = βˆ

1x. Hint: Sxy/Sxx is not the

correct answer. You might have to look at minimizing SSE.
Bonus: Find V (βb1) for you estimate from #10.
