QSTAT2: MATLAB function to compute Ljung-Box Q statistic
This MATLAB function computes the Ljung-Box 'Q' statistic, or portmanteau test, for autocorrelation in a timeseries. It is often applied to regression residuals as a diagnostic. The calling program specifies one or more lag lengths. QSTAT2 returns one or more test statistics and associated P-values. Various utility routines from Jim LeSage's Econometrics Toolbox (q.v.) are required. Also see Kanzler's QSTAT on this archive.
