predict.loclda: Localized Linear Discriminant Analysis (LocLDA)
Description
Classifies new observations using parameters determined by
the loclda-function.
Usage
## S3 method for class 'loclda':
predict(object, newdata, ...)
Arguments
object
Object of class loclda.
newdata
Data frame of cases to be classified.
...
Further arguments are ignored.
Value
A list with components:
classVector (of class factor) of classifications.
posteriorPosterior probabilities for the classes.
For details of computation see loclda
(+ normalization so posterior-values add up to 1 for each observation).
all.zeroVector (of class integer) indicating for which rows of
newdata all corresponding posterior-values are $< 10^{-150}$ before normalization.
Those observations are assigned to the class to whose (locally weighted) centroid they have the
lowest euclidian distance.
