align_new: Align New Functions to a Fitted Template

In fdasrvf: Elastic Functional Data Analysis

Align New Functions to a Fitted Template

Description

This function aligns new functions to the template SRVF (mqn) of an fdawarp object with the same lambda, penalty and optimization method used by time_warping() to fit it. When the fit smoothed the data (smooth_data = TRUE), the new functions are smoothed the same way first.

Usage

align_new(x, f_new)

Arguments

x	An object of class fdawarp typically produced by time_warping().
f_new	A numeric matrix of shape M \times K of K new functions sampled at x$time, or a numeric vector of length M for a single function.

Value

A list with components (one column per function):

• fn: M \times K aligned functions;

• qn: M \times K aligned SRVFs;

• gam: M \times K warping functions.

Examples

## Not run: 
out <- time_warping(simu_data$f, simu_data$time)
aligned <- align_new(out, simu_data$f[, 1:3])

## End(Not run)
