regmod_prediction

Description

Performs the Wasserstein regression using quantile functions.

Usage

regmod_prediction(data, xpred)

Arguments

data

A bregmod object.

xpred

A kxp matrix of input values for regressors for prediction, where k is the number of points we do the prediction and p is the dimension of the input variables.

Value

A kxm array. Qpred(l, :) is the regression prediction of Q given X = xpred(l, :)' where m is the dimension of the grid of quantile function.
