[ncl-talk] How can i get the effective number of degree of freedom during the correlation signficant test?

[Hyun Marcia]

Hello,

I want to get a effective number of degree of freedom during the
correlation.

When i use two data like this

X (time)  Y(time lat lon)

I'm trying to calculate a (95%) confidence level on a correlation/regression
map  of X & Y

But i cant understand how to use this function in significant of correlation
coeff.

Can i apply equiv_sample_size

  when i use rtest function?

Is there anyone who help this problem?
