I insist on GWR. To run a GWR model I'm using both R and GWR 3.0. Comparing
the estimated coefficients for an adaptative bisquare kernel in R with the
results for an adaptative kernel in GWR 3.0 (which is supposed to be a
bisquare function too), differences are very big. I check the bandwidths and
they are not that different (as I understand, in R the adaptative bandwidth
is expressed as a percentage of observations, while in GWR 3.0 the bandwidth
is the number of observations itself). But anyway, the estimated
coefficients shouldn't be so different, should they?
