Computes sample cross-correlation matrices of a multivariate time series, including simplified ccm matrix and p-value plot of Ljung-Box statistics.
ccm(x, lags = 12, level = FALSE, output = T)
A matrix of vector time series, each column represents a series.
The number of lags of CCM to be computed. Default is 12.
A logical switch. When level=T, numerical values of CCM is printed. Default is no printing of CCM.
A logical switch. If ouput=F, no output is given. Default is with output.
Sample cross-correlation matrices
p-values for each lag of CCM being a zero matrix
The p-value of Ljung-Box statistics does not include any adjustment in degrees of freedom.
