Webb12 maj 2010 · A general pattern is for the trend’s acf is to be slowly decaying. This means that there are strong correlations from past values. Sometimes this is due to the underlying data being non-stationary. For the seasonal’s acf, it can appear oscillotary as well. WebbThe acf is clearly declining very slowly in this case, which is consistent with their being an autoregressive part to the appropriate model. The pacf is clearly significant for lags one …
