gwr.gauss | R Documentation |
The gwr.gauss function returns a vector of weights using the Gaussian scheme:
w(g) = e^{{-(d/h)}^2}
where d
are the distances between the observations
and h
is the bandwidth.
The default (from release 0.5) gwr.Gauss function returns a vector of weights using the Gaussian scheme:
w(g) = e^{-(1/2) {{(d/h)}^2}}
gwr.gauss(dist2, bandwidth)
gwr.Gauss(dist2, bandwidth)
