Mean Function for Multivariate Functional Data

Description

Computes the mean function for an object of class mfd.

Usage

## S3 method for class 'mfd'
mean(x, ...)

Arguments

x	An object of class mfd, containing N observations of a p-dimensional multivariate functional variable.
...	Further arguments are ignored (required for S3 consistency).

Details

The method averages the coefficient array across the observation dimension, resulting in a new mfd object with one observation (the sample mean).

Value

An object of class mfd representing the mean function. The output contains a single observation, corresponding to the mean function for each variable.
