[R-sig-Geo] A question about the estimated standard errors in SPGWR package

I have a simple question about the estimated standard errors obtained from
the gwr command in SPGWR package. I run a GWR regression y~x
In the data frame
there are two estimated standard errors for the x coefficients denoted as
x_se and x_se_EDF.
What is the difference between x_se and x_se_EDF and what is the best for
use, the former or the latter? The manual lacks information about this.
If I am not confused I think that the difference should be in the
approximation of hat matrix that is x_se uses s^2 with approximation
whereas x_se_EDF not.
I would appreciate any help.
Thanks in advance
