Re: [ferret_users] Can ferret consider EDOF(effective degree of freedom) when calculate correlation?

Ferret doesn't include anything that uses "effective degree of freedom".  If you have a method, perhaps using python or another piece of software, you could list data from Ferret in an appropriate way.

Student T-test can be used for figuring out the significance level. however, it's known that the effective degree of freedom (Davis 1976, "Predictability of Sea Surface Temperature and Sea Level Pressure Anomalies over the North Pacific Ocean") need to be consider instead of using "N-2" for comparing two variables which are closely related, such as local sea surface temperature and global sea surface temperature.
