s/n | Time lags | R algorithm |
|---|---|---|
1 | The corresponding to an estimated value for the AutoCorrelation Function (ACF) | acf {stats} |
2 | The corresponding to a statistical important estimated value for the ACF. If there is no statistical important estimated value for the ACF, the corresponding to the largest estimated value | acf {stats} |
3 | According to nnetar {forecast}, i.e. the time lags 1, …, n, where n is the number of AutoRegressive (AR) parameters that are fitted to the time series data | ar {stats} |
