nadayara_prediction

Description

Functional non-parametric Nadaraya-Watson prediction with 2-Wasserstein distance.

Usage

nadayara_prediction(nadaraya, Qpred, hs=NULL)

Arguments

nadaraya

A Nadaraya regression object.

Qpred

Quantile curves that will be used in the predictions

hs

Smoothing parameters for the predictions, by default hs = seq(0.8, 15, length = 200)

Value

An object of class bnadarayapred: prediction The Nadaraya-Watson prediction for the test data at each value of hs. hs Hs values used for the prediction.
