This is why in forecasting and time series analysis is used the log difference, a 10% increase or decrease on the log scale gives you the same value being added or removed.
Yes, that requires a reference value to be decided upon beforehand.
Not really, you do t=n and t=n+1, for n= 1, 2, 3 for a quick view on volatility.
Then ypu look up for correlations between e[t=n | t= 0, t= 1...] for different Ns. For more I would need to check out my notes
Oh I was imagining something entirely different. Like a simple logarithmic scale of a signal, I do not know anything about time series analysis. Should've kept my mouth shut
