Avoid silly mistakes in Simple Linear Regression in the university exam


  • Basic knowledge of Simple Linear Regression so that you could understand the mistakes mentioned


The purpose of this econometrics course is to share with you the confusion points and some of the silly mistakes that students do while studying Simple Linear Regression.

Mistake 1: Placement of error term in population & sample regression equations. Also, have you ever seen 'X hat' in any of the regression equations?

Mistake 2:
What is it that we minimise in the method of OLS?
Do you first sum the sample errors and then square the sum?
Do you first square the sample errors and then take the sum?

Mistake 3:
Not practicing the mathematical expressions. There are multiple ways of writing the formula for 'B2 hat'. Do you know all of them?

Mistake 4:
You must have encountered some assumptions while studying Simple Linear Regression. Do you put the assumptions on the sample error? Also, what is the mathematical expression for the sample error?

Mistake 5:
Not paying enough attention to the assumptions and linkages.
Example: What do you think about the following two statements? True or False.
Statement 1: In the presence of heteroscedasticity, the OLS estimators are biased.
Statement 2: For OLS estimators to be BLUE, the population error should follow a normal distribution.

Mistake 6:
Standard Deviation OR Standard Errors?

Mistake 7:
Testing the hypothesis on estimators or parameters?

So, what are you waiting for? Get started with the course so that you don’t make the same mistakes in your final exam!

Author of two e-books on Amazon (One for Statistics and one for Econometrics). I have 1500+ hours of teaching experience in the field of Microeconomics, Statistics and Econometrics. I became an online tutor in 2015 and have been teaching full time since then. I have worked with students who were complete beginners, as well as those who were facing challenges in mastering advanced topics.

I completely understand the initial struggle in decoding the concepts and formulas. I am adept in breaking down difficult concepts with the use of simple examples. I don't encourage memorisation and simply recalling the formulas, instead, I focus on the 'why' and 'how'.

I understand that every student has a different way of understanding things. Some students understand the concepts when explained through analogies, others when shown mathematical foundation behind them. I modify my teaching methodology depending on what the student is comfortable with.
