predict.fda(object, x, type, prior, dimension)
object |
An object of class fda . |
x |
New data at which to make predictions. If missing, the training data is used. |
type |
kind of predictions: type = class (default)
produces a fitted factor, type = variates produces a
matrix of discriminant variables, type = posterior
produces a matrix of posterior probabilities (based on a
gaussian assumption), and type=hierarchical produces the
predicted class in sequence for models of all dimensions. |
prior |
the prior probabability vector for each class; the default is the training sample proportions. |
dimension |
the dimension of the space to be used, no larger
than the dimension component of object . |
An appropriate object depending on type
