eliminating constant variables
Hi all,
I have a large data set and want to immediately build a 'blind' model
without first examining the data. Now it appears in the data there are a lot
of fields that are constant or all missing values - which prevents the model
from being built.
Can someone point me the right direction as to how I can automatically purge
my data file of these useless fields.
Thanks in advance,
pdb
