I am exploring the use of GWmodel to run some GWR regressions. I set it up and tried to run some sample regressions using the gwr.basic function, but ran into the following error,
Error in t(X * W.i) : dims [product 4659] do not match the length of object [0]
This is what I did,
gwr.basic(Y~X+I(X^2), data = spdf,bw = bw.gwr.1, kernel = "gausssian", adaptive = TRUE, F123.test = TRUE)
And here is the summary of my input data set, spdf
**summary(spdf)
