Again, we should check that our model is actually a good fit for the data, and that we dont have large variation in the model error, by running this code: As with our simple regression, the residuals show no bias, so we can say our model fits the assumption of homoscedasticity.

Basically, there are three types of regression for panel data: 1) PooledOLS: PooledOLS can be described as simple OLS (Ordinary Least Squared) model that is performed on panel data.
