predict.gcdclust: make predictions from a "gcdclust" object.

In KarimOualkacha/HHSVM-ClusterNet: hhsvm classification using the cluster elastic net penality

Description

Similar to other predict methods, this functions predicts fitted values and class labels from a fitted gcdclust object.

Usage

## S3 method for class 'gcdclust'
predict(object, newx, s = NULL,
type=c("class","link"), ...)

Arguments

object	fitted gcdclust model object.
newx	matrix of new values for x at which predictions are to be made. NOTE: newx must be a matrix, predict function does not accept a vector or other formats of codenewx.
s	value(s) of the penalty parameter lambda at which predictions are required. Default is the entire sequence used to create the model.
type	type of prediction required. Type "link" gives the linear predictors for classification problems and gives predicted response for regression problems. Type "class" produces the class label corresponding to the maximum probability. Only available for classification problems.
...	Not used. Other arguments to predict.

Details

s is the new vector at which predictions are requested. If s is not in the lambda sequence used for fitting the model, the predict function will use linear interpolation to make predictions. The new values are interpolated using a fraction of predicted values from both left and right lambda indices.

Value

The object returned depends on type.
