discRob
discRob
object.
crossvalidate.discRob(object, doubt=0, digits=.Options$digits, trace=T, subset)
discRob
object constructed by the
discRob
function.
doubt
<
(g-1) / g
, where
g
is the number of groups,
defining the minimum difference the maximum posterior
probability of group membership must exceed all others
before assigning the observation to that group. If there
does not exist a posterior probability of a group
membership for an observation that exceeds
doubt + 1/g
, the observation
is assigned to an "unknown" group.
group
factor
column followed by the posterior probability of group membership for each
observation in the
newdata
data frame or the
training data.
Performs crossvalidation of the discriminant function contained in
object
. This function may take a considerable
amount of time to compute the leave-one-out error rate.
