WebJan 4, 2024 · Thus, linearity in parameters is an essential assumption for OLS regression. However, whenever we choose to go for OLS regression, we just need to ensure that the ‘y’ and ‘x’ (or the transformed ‘ y’ and the transformed ‘ x’) are linearly related. The linearity of β’s is assumed in the OLS estimation procedure itself.
