Question: 3. Bias. Let r;, i = 1, ..., n be constants. Suppose Yi = Bot BITit ci Recall that B1 = ZLI(Ti - I)(yi -

3. Bias. Let r;, i = 1, ..., n be constants. Suppose Yi = Bot BITit ci Recall that B1 = ZLI(Ti - I)(yi - y) ELI(; -I)2 Show that B, is unbiased. In other words, start with E(B) = E EN(Ti - I)(yi - y) ELI(I; -I)2 and work until you end up with E(B1) = BI- Hint: don't forget that Bo and B, are parameters and are therefore constants
