thanks for help,
I have a data.frame "newData" with 7 columns and 91 rows. i wish to find the
row in the second column "X" with the max value and save all 7 values (=all
columns) in a new data.frame
# max value result for row
Max.Result <- max(newData$result)
select the row with the max value

Based on the output you provided, apparently these NAs are either
ignored or treated as zeros. When you got a CV score as zero, you shall
be aware that there is definitely a problem (all the adaptive qs produce
the same 0, that means you are basically regression the dependent
Hi!
I'm trying to use GWR with a dataset who has a lot of NAs. How spgwr
considers NAs?
As a test, I'm having the following results:
> g.adapt.gauss.00 <- gwr.sel(pib00 ~ cv00 + le00 + ma00 + ou00, data=dados,
adapt=TRUE, coords=cbind(dados$x, dados$y))
Adaptive q: 0.381966 CV score: 0
