nadayara_regression

Description

Functional non-parametric Nadaraya-Watson regression with 2-Wasserstein distance, using as predictor the distributional representation and as response a scalar outcome.

Usage

nadayara_regression(data, response)

Arguments

data

A biosensor object.

response

The name of the scalar response. The response must be a column name in data$variables.

Value

An object of class bnadaraya: prediction The Nadaraya-Watson prediction for each point of the training data at each h=seq(0.8, 15, length=200). r2 R2 estimation for the training data at each h=seq(0.8, 15, length=200). error Standard mean-squared error after applying leave-one-out cross-validation for the training data at each h=seq(0.8, 15, length=200). data A data frame with biosensor raw data. response The name of the scalar response.
