I was wondering if someone could help explain cross correlation to me with the data i have available.
I have two time series
One is how variable X changes each month over 133 months
the other is how variable Y changes month over 133 months
I'm using mini tab and i've set the LAG to 25% (33) as i wasn't sure what it should be and it produces a graph that i've copied in.
Can someone give me an insight into what i'm looking at?
I know this sounds really stupid but i'd love for someone to explain what the chart is actually demonstrating.
