Dear user´s of S+SaptialStats v1.0 or 1.5 for Windows.
I'm working with S+plus 2000 r.3 for Windows, and i traying to fit a
variogram to a "PM2.5" data grid, but i have some outliers in the variogram
cloud, so when i removed a pair of them by the optional argument "subset",
and look again the variogram cloud, another outlier apperas, but it's
identified with the same number of ones that i remove before.
What happend with the order of my rows, is it re-order?
{example: one of my outliers is the pair (1,13) so i remove it by
subset=-c(1,13)
but in the new variogram cloud appears another outlier pair (7,13) }
Do i removing just the pair (1,13) or i'm removing the row 1 and row 13?
'cause i don't understand.
I'll appreciate your attention
Regards
