Effective number of parameters (enp)

Hello all,

I am trying to interpret the model output from the geographically weighted regression R function ?gwr' in the package ?spgwr?. 

There are two ?effective number of parameters?:
Effective number of parameters (residual: 2traceS - traceS?S)
Effective number of parameters (model: traceS)

How do I interpret them? Do you know which one is for the calculation of adjusted p values addressed here <https://github.com/cran/GWmodel/blob/master/R/gwr.t.adjust.r>?

Thank you,
Dongmei
