`acf_seasonalDiff.Rd`

Autocorrelation coefficients based on seasonally differenced series

acf_seasonalDiff(y, m, lagmax)

y | a univariate time series |
---|---|

m | frequency of the time series |

lagmax | maximum lag at which to calculate the acf |

A vector of 3 values: first ACF value of seasonally-differenced series, ACF value at the first seasonal lag of seasonally-differenced series, sum of squares of first 5 autocorrelation coefficients of seasonally-differenced series.
