Hi,
I have two questions about ccf. 1) does it return correlation value for each
lag? The documentation states the following: "The lag is returned and
plotted in units of time, and not numbers of observations. There are
printand subsetting methods for objects of class
"acf" ". Does this mean only lag values are returned, and if plot is turned
off, then we won't know the calculated correlation value for each lag? Is
there a way to display both the lag and its corresponding correlation value
in text? 2) Is the lag used for ccf always in units of time? The
documentation states: "The lag is returned and plotted in units of time, and
not numbers of observations.". This makes sense for acf, but does ccf lag
also use units of time instead of observations?
Thanks,
Tom
