Thanks Imy! Really appreciate the feedback and I am glad you found it useful :)

The ending is good. Why we need to make a time series stationary? I never had a clear idea as I was following most books, which they just do it as a ritual.

[@egorhowell]

Thank you! Glad it made sense :)

[@RajaReivan]

does the series still have some seasonality component after being transformed with differencing and log? which means it is still non-stationary, but why did the adf test show that it's stationary?, can u help explain this?

[@egorhowell]

There may be some seasonality, but it might be so small that it is statistically insignificant

[@daansan26]

Well explained!

Thanks David!
