partial correlation function for multivariate time series
Dear all,
I found the following behaviour with pacf() in the multivariate case,
set.seed(10)
x <- rnorm(1000,sd=10000)
y <- rnorm(1000,sd=1)
pacf(ts(cbind(x,y)),plot=FALSE,lag.max=10)
Partial autocorrelations of series 'cbind(x, y)', by lag
, , x
x y
