Moving window for time series data

NettetYou can think of it as shifting a cut-out window over your sorted time series data: on each shift step you extract the data you see through your cut-out window to build a new, smaller time series and extract features only on this one. Then you continue shifting. Nettet5. aug. 2024 · The time has come to finally explore the most fundamental time series forecasting model — simple moving averages (MA). We’ll cover the basic theory …
