predict.samLL: Prediction function for S3 class "samLL"

Description

Predict the labels for testing data.

Usage

## S3 method for class 'samLL':
predict(object, newdata, thol = 0.5, ...)

Arguments

object

An object with S3 class "samLL".

newdata

The testing dataset represented in a n by d matrix, where n is testing sample size and d is dimension.

thol

The decision probability threshold for prediction. The default value is 0.5.

...

System reserved. (No specific usage)

Value

• probs
  Estimated Posterior Probability for Prediction also represented in a n by the length of lambda matrix, where n is testing sample size.
• labels
  Predicted labels also represented in a n by the length of lambda matrix, where n is testing sample size.

Details

The testing dataset is rescale to the samLLe range, and expanded by the samLLe spline basis funcions as the training data.
