CROSSCORR - Graphical display of cross-correlations
Posted: Wed Jun 29, 2011 1:04 pmThis procedure computes and graphs cross correlations between two series. The graph is shown as a 2x2 matrix with autocorrelations for the series in the diagonal slots and the cross correlations in the off-diagonal with the leads in one corner and lags in the other.
@CrossCorr( options ) series1 series2 start end
Parameters:
series1 series2 Pair of series to analyze
start end Range over which to compute correlations. By default, the common range of the two input series.
Options:
[GRAPH]/NOGRAPH Do High-resolution graphs?
SPIKE/[NOSPIKE]
NUMBER=number of autocorrelations to compute [depends upon data]
WINDOW=title for graph window
REPORT/[NOREPORT]
PRINT/[NOPRINT]
Example:
From Diebold's Elements of Forecasting. This uses BJIDENT to show the univariate autocorrelations and CROSSCORR to show the cross correlations.
