Is converting the variables as stationary the right choice?
I am working on time series regression OLS based on log variables and stationary dependent variables. While experimenting, my results were not that significant, and during analysis, I also felt like the graphical results didn't provide me with a meaningful outcome.Â
Â
Can anyone help me in understanding what needs to be done here?

It is essential to do a stationary test before executing OLS. However, if you plan to use non-stationary variables in the regression methods, the process will give you spurious results.

Still, the problems are faced by the researchers when it comes to causality. But a unified theory will help the researchers to use statistical methods for predicting the future, and it will be helpful while experimenting with the results.

I agree with @Rohan Maggoo. We need a proper theory on using statistics in experimental studies to manage the causality, which cannot be resolved quickly.  Making the data stationery is a necessary process that you cannot avoid. If you try to use it without converting the data stationary, then spurious correlation will become a dilemma.  Please check the below link to know more about Regression models,  https://bookdown.org/rushad_16/TSA_Lectures_book/regression-models.html  Good Luck

Hello Bob,
Â
If your variables are non-stationary in an OLS regression will not provide you a meaningful result and probably will end up with spurious results. And it is the best choice to make your variables stationary to avoid spurious regression and unpredictable outcomes. Moreover, make your independent variables as well as dependent variables as stationary data.

Good Luck
