AI Thread Summary
The discussion centers on a university student struggling with econometrics proofs in their third-year economics course. They seek guidance on understanding specific proofs and express a desire for resources rather than direct answers. The student plans to consult their textbook for clarification after finding the lecture material challenging. They mention an easier proof related to expected values and inquire about the implications of a "linear model." Overall, the thread emphasizes the need for direction in mastering econometric concepts.

Hey everyone,
I'm doing an 3rd year economics course in university and I'm already running into difficulty trying to show proofs of the following:
Q3 and 4.png


Now I certainly don't wish to ask for spoon feeding just some direction or source to where I can look up and read for the solution. My knowledge on these are still weak and the deadline is by the end of this Friday. I'm going to try the textbook tomorrow to see alternatives because I couldn't understand the lecture as well as I had hoped.

Thank you

3a is easy: [math]E\left(\sum X_I\right)= \sum E(X_I)= \sum \beta= n\beta[/math] so the expected value of [math]\frac{1}{n}\sum X_i[/math] is [math]\beta[/math].

Pretty much the same thing for 3b.

For 4, what does "linear model" imply?
