Displays the autocorrelation and partial correlation functions of the squared residuals from an estimated equation, together with the Q-statistics and p-values associated with each lag.

You must specify the largest lag n to use when computing the autocorrelations.

displays the correlograms of the squared residuals of EQ1 up to 24 lags.

See “Autocorrelations (AC)” and “Partial Autocorrelations (PAC)” for a discussion of autocorrelation and partial correlation functions, respectively.
