Subject: Effective degrees of freedom
Greetings,
I am performing a simple Pearson's correlation test. Length of both
vectors is 40, therefore the resulting df is 38. Nevertheless, a
colleague is asking me for the "effective degrees of freedom". As far as
I understand, those degrees of freedom have to be estimated for more
complex regressions, but I was not able to find detailed information
about it. Does any one of you know if I have to estimate those effective
degrees of freedom for a simple Pearson correlation test?
Thank you very much in advance,
