This course focuses on the fundamental concepts required for the analysis, modelling and forecasting of time series data and provides an introduction to the theoretical foundation of time series models alongside a practical guide to the use of time series analysis techniques implemented in Stata 16. The residual sum of squares is shown as each one is added, ending at 3138 with a BIC of 1114, notably lower than the 1386 of the one-threshold model. After 4 scans through the data, we get four threshold points. These indicators are: 1.
