classres
is used to store results classification for one or multiple classes.
classres(c.pred, c.ref = NULL, p.pred = NULL, ncomp.selected = NULL)
matrix with predicted values (+1 or -1) for each class.
matrix with reference values for each class.
matrix with probability values for each class.
vector with selected number of components for each class.
predicted class values (+1 or -1).
predicted class probabilities.
reference (true) class values if provided.
The following fields are available only if reference values were provided.
number of true positives.
nmber of false positives.
number of false negatives.
specificity of predictions.
sensitivity of predictions.
There is no need to create a classres
object manually, it is created automatically when
build a classification model (e.g. using simca
or plsda
) or apply the
model to new data. For any classification method from mdatools
, a class using to represent
results of classification (e.g. simcares
) inherits fields and methods of
classres
.
