Key Assumptions of OLS: Econometrics Review
While OLS is computationally feasible and can be easily used while doing any econometrics test, it is important to know the underlying assumptions of OLS regression. This is because a lack of knowledge of OLS assumptions would result in its misuse and give incorrect results for the econometrics test completed.

The Ultimate Properties of OLS Estimators Guide
Linear regression models have several applications in real life. In econometrics, Ordinary Least Squares (OLS) method is widely used to estimate the parameters of a linear regression model. For the validity of OLS estimates, there are assumptions made while running linear regression models.
