I am using
ccf to find a correlation between 2 time series. I am getting a plot that looks like that:
Note that I am mainly interested in correlation for the lag=0. Questions:
- Do interpret it correctly that there is a cross-correlation for the lag=0, as for this lag the cross-correlation is above the dotted line?
- How should I interpret the level of cross-correlation in this example, is this significant (as I interpret it right now, there is a small cross-correlation)?
- How can I extract only
acfvalue for lag=0?
