Dear List,
I am using errorsarlm (spdep) to measure SAR autocorrelation but failed as
detailed below.
system: windows XP and Vista
RAM : 2G (XP) and 4G(Vista)
sample size : 4500
variable: 4
nb10<-dnearneigh(coords,0,9)
the error issue: out of memory of 180 Mb
The similar messages in the archive were checked and tried but failed to
solve the issues.
1. enlarging the R space to 2047 Mb
2. updating the neighboring unit from 0.5 to 9
Please kindly help how to solve the problem, for I found SAR and CAR seem to
be more reliable for autocorrelation than autocovariate.
Thanks
Elaine
