Hi Sandeep,

Do you have, for each year, correlation r in XY dimension ? I mean r for each grid point of XY for each year ? Also can you elaborate the dimensions of two data sets ?

Hi,
can anyone tell me how to do 21 yr running correlation in ferret between two data sets.

Dear Ryo,

Are you saying that the plot of such running correlation and trends will be like a time series ?

I'm sorry, Saurabh, Sandeep, and other Ferret users. I've begun to think that my idea was wrong. I thought @SBX was the solution, but it doesn't keep the same mean value over the window, in formulae like

u' = u - mean(u).

So, indeed the correct solution would be complicated. I'd like to know if there is an elegant solution.
