WebAug 13, 2024 · PACF is the partial autocorrelation function that explains the partial correlation between the series and lags itself. In simple terms, PACF can be explained using a linear regression where we predict y (t) from y (t-1), y (t-2), and y (t-3) [2]. In PACF, we correlate the “parts” of y (t) and y (t-3) that are not predicted by y (t-1) and y (t-2).
