Hi all,
I was wondering if anyone could help me out with the following problem;
For my study I’m investigating if a change in GDP of a country is correlated to the number of Patents granted in the same country. I’ve collected 27 years data of GDP & granted Patents (data collection per year).
I’ve read about correlation of time-series, but I’m not sure how to handle this problem. Both the GDP and Patent numbers tend to grow over time, so I suspect a correlation simply because of the increasing trend? Is it possible to “filter” out this trend? Or this is not needed at all?
I hope someone can explain this is a simple manner, since I’m not quite that experienced with statistics
. It is possible for me to use Excel or SPSS.
Thank you in advance.
