GWR Gaussian weights function
gwr.gauss.RdThe 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)
Arguments
| dist2 | vector of squared distances between observations and fit point |
|---|---|
| bandwidth | bandwidth |
Value
vector of weights.
