WebValidating and testing a time series model. Among the factors that make time series forecasting challenging are: Time dependence of a time series - The basic assumption of a linear regression model that the observations are independent doesn’t hold in this case. Due to the temporal dependencies in time series data, time series forecasting cannot … WebIntroduction¶. A time series is a succession of chronologically ordered data spaced at equal or unequal intervals. The forecasting process consists of predicting the future value of a time series, either by modeling the series solely based on its past behavior (autoregressive) or by using other external variables.
