Consider a simple one-way Analysis of Variance model: yi =B o +3 ; + e; for i = 1, ...,n where e1, ..., en are mean zero and uncorrelated errors. For each of the following parameter functions, specify whether they are estimable or not. If estimable, provide their least squares estimate. If not, explain why.
a) Bo +B2
b) B1
c) B1-B2
d) B1+B2+B3-3B4
