Hello

I am running a Kriging cross validation in Automap. I get the following
error


"chfactor.c", line 130: singular matrix in function LDLfactor()

I did check out the troubleshooting part of gstat manual which

suggested two possible reasons



during simulation, when an observation falls almost exactly at a simu-
lation location. Solution: increase the value of zero

when two observations occur at identical location occur and noaverage
or average=0 was dened in a data denition. Solution: remove the
noaverage, or add average=1


Can someone elaborate what exactly is to be done in the above two options
as i am finding it a bit cryptic.
