Hello, thank you for interesting lessons. I have a question. Time series analysis is only analysing dependency betwee values (Y) and time periods? For example, I conduct research with analysis of gas consumption. This is seasonal time series but to predict gas consumption, it is not enough to take into consideration the previous gas consumption but also temperature of the air, humidity, types of consumers etc. It is like high dimensioanl model where time is actually one of dimension. Can we consider this as a time series as well? Thank you!
