Hi,

I am trying to use a spatially adaptive kernel in spgwr and I have some
questions.

I am using the following code:
col.d <- gwr.sel
(ResponseTime~IsRural+IsSemiRural,data=sb,coords=cbind(sb$Longitude,sb$Latitude),gweight=
gwr.bisquare,longlat=TRUE)

First, I keep getting a CV score of "NA" for each result returned. What does
this mean? I do not have any missing values in any observations. Also, while
gwr.sel is running, results are printed to the screen, but what does each
line of ouput represent? Each regression point?

Finally, is gwr.sel expected to take a very long time to complete? I have
19,000 data points that I am hoping to use for a GW regression but so far
only two lines of output have been printed to the screen after about 4
hours.

I apologize in advance for the naivete of my questions, but I am a newbie
;-).

Thanks,
Ryan
