random forest problem when calculating variable importanc e
Are the results dramatically different?
The result would be expected to be somewhat different, as setting
importance=TRUE would make many calls to the random number generator (for
permuting OOB data in each variable), making all but the first tree in the
forest different than if importance=FALSE.
