Hi all, can any body clarify me why the degrees of freedom in R output
of ?GWR comes in decimal? Mike
Please read the references, where this is explained - why would you expect
them to be integer when weighted proportions of observations are being
used for each fit point? The print method for fitted gwr objects reports
two versions of effective degrees of freedom if the hat matrix is
computed, one complete, the other an approximation used in the 2002 GWR
book, but these non-integer numbers are also based on assumptions.
