WebJun 10, 2024 · The main benefit is that you have smaller code base by not writing specific code for OLS and using the generic code for GLM, it's easy to try different settings in more generic code and probability of bugs is lowered too. This happens to me sometimes. I have the scripts to run ARIMA, and run ARIMA (0,0,0) for a OLS regression too.
