Hi,
I am helping someone to analyze a data set .
He had to make periodogram, correlogram, and partial correlogram, I made them using excel add ins , but I do not know how to interpret its graphic representation.
Can some one give me a link to the resource material for interpretation of the graphs?
I would really appreciate that.
Thank you
